Abstract:

Inorganic/polymer hybrid hydrogels generally exhibit excellent mechanical properties, while extra function include luminescence are extremely explored due to the further application in sensors and optoelectronic devices. Herein, we report the rare-earth (RE) complex/silica nanoparticles (SNs) luminescent hybrid polyethylene glycol (PEG) hydrogels showing stable luminescence. The hybrid hydrogels coordinated with RE (Eu3+) complex are fabricated via a convenient in situ photocrosslinked procedure. The coordination polymers showed red luminescent color under the 365 nm UV irradiation. Furthermor

Abstract:

Luminescence Properties Of Nanocomposite (Zinc Oxide/Polyethylene Glycol: Lithium ions) have been synthesized using different molecular weight of polymer. Changing the molecular weight produced no effect of the crystallinity of ZnO nanoparticles if similar molarity of ethylene glycol unit were used. However, the use of high molecular weight of polymers tended to reduce the size of nanoparticles, which implied to the enhancement in the luminescence spectra due to increasing in the particle number concentration.

Abstract:

Transparent luminescent TiO2/polymer nanocomposites were obtained through the combined use of copolymerization of a novel titanium ion containing monomer with a liquidsolid reaction. The titanium ions are covalently introduced into polymer chains and transformed into TiO2 nanocrystals directly in the solid-state polymer matrices. That allows the generation of high-quality anatase TiO2 nanocrystals with a narrow size distribution in the polymer matrices. The luminescence of the TiO2 nanocrystals is dominated by band-edge luminescence at room temperature.

Abstract:

Metallic mercaptides are inert organic compounds (i.e., Mex( SR) y) that can be used to make thermoplastic polymers high luminescent to UV-light. Luminescence is strictly required in polymer manufacturing since this characteristic allows detection of polymer pieces by photoelectric sensors. Luminescent Au, CdS, and ZnS nanoparticles can be generated into thermoplastics like: polystyrene, polycarbonate, poly(vinyl acetate), etc. by thermolysis of the corresponding mercaptides. PL spectra of polymeric films embedding these nanoparticles show intensive visible light emission in different spectral

Europium-doped strontium aluminate is a famous green phosphor that can give luminescence under a mechanical stress that is named elastico-luminescence. This paper reports a modified reverse micelles process for preparing the europium-doped strontium aluminate nanoparticles. A polymeric matrix was coated on the surface of the precursor formed in the reverse micelles. The polymeric matrix is considered to prevent the particle agglomeration by forming a carbon layer while the precursor was heat-treated. Consequently, the luminescent nanoparticles were achieved after removing the carbon layer and

Abstract:

Gold thiolate polymers ([ArSAu]n) were prepared via two synthetic routes - the direct reaction of an aromatic thiolate (ArSH) with HAuCl4, or the reaction of an isonitrilegold(I) chloride complex with a thiolate anion. The former route, which is general to almost all thiols, yields an amorphous and non-luminescent material. The latter route, which is more limited in scope, proceeds via an isonitrilegold( I) thiolate complex and typically yields a crystalline and luminescent material. Addition of electron-donating groups to the thiol aromatic ring leads to more rapid polymer formation and loss

Abstract:

The behaviour of the luminescence spectra of the organic dye R6G in a multiple scattering polymer matrix was studied with reference to the parameters of the scattering media. It was found that some of the luminescent parameters depend on the concentration of scattering particles, the refractive index of the scattering particles and the sample thickness. As it was shown, that the reason for these dependences is the reabsorption of luminescence light enhanced by multiple light scattering. In addition, an increase in the absorption caused by multiple scattering was observed.

Abstract:

AbstractThe paper reports on the dependence of the absorbance and luminescent intensity from pH of novel poly(oxyethylene phosphate) tris(β-diketonate) europium (III) complexes. The photophysical data obtained allow some preliminary assumptions about the nature of this phenomenon. Increase in luminescent efficiency is a consequence of enhanced efficiency of energy transfer caused by structural changes in complexes after water deprotonation. Remarkable change has been observed in photophysical properties of the polymer complexes by studying the fluorescent emission and excitation spectra and ab

Abstract:

In this work, photoluminescent properties of Ru (bpy)32+ incorporated in cellulose nanofiber (CNF) film was investigated by comparing with those in polyvinyl alcohol (PVA) and polyacrylic acid (PAA) films. In the polymer films, the luminescence intensity of Ru (bpy)32+ was high and λmax of luminescence spectra was blue-shifted compared with those in aqueous solution. The high luminescence intensity was also observed in cellulose nanofiber (CNF) films but the spectrum was red-shifted. Luminescence decay measurement showed that the decays in polymer films were exponential and the lifetimes were

Abstract:

Rare-earth-doped optical materials are important for light sources in optoelectronics, as well as for efficient optical amplification elements and other elements of photonics. On the basis of the previously developed method of anhydrous, low-temperature synthesis of Er/Yb oxides from their chlorides we fabricated proper nanoparticles with defined parameters and used them for the development of optically transparent, luminescent polymer nanocomposite with low optical scattering, suitable for direct, light-induced formation of photonic elements.

Abstract:

Polymer luminescent compositions based on polystyrene (PS), polycarbonate (PC) and polymethyl methacrylate (PMMA) doped with boron difluoride dibenzoylmethanate (DBMBF2), boron difluoride anthracenoylacetonate (AntAcBF2) and their mixture were investigated. Composition based on PS has a maximum quantum yield of luminescence. The role of PS in increasing the efficiency of energy transfer from the donor (DBMBF2) to the acceptor (AntAcBF2) is revealed, which is due to the formation of exciplexes between DBMBF2 and phenyl rings of PS.

AbstractTwo well defined, blue luminescent homopolymers containing 9,9-diethylfluorene core with electron withdrawing pendant pyridine, Suzuki-coupled with the corresponding borolane of decoxy phenyl (PFPA) and naphthalene (PFNA) have been designed and synthesized efficiently. The obtained rod-coil polymers have the average molecular weight of 15212 (PFPA) and 15130 (PFNA) with polydispersity indices (PDIs) 1.07 and 1.3, respectively. The polymers have good solubility and high thermal stability with the decomposition temperature of 362 °C (PFPA) and 367 °C (PFNA) correspondingly. Furthermore t

Abstract:

In this work, we present a novel pyrene-functionalized benzoxazine (Py-BZ)/single-walled carbon nanotubes (SWNTs) complex material as an efficient luminescent chemosensor for gaseous amines. It is shown that an interaction of poly(Py-BZ)/SWCNTs nanocomposites with analyte vapor leads to the increase of the intensity of luminescence. The response of these sensors to methylamines by static and dynamic flow measurement were studied.

Abstract:

The excitation and emission spectra of polymeric matrices—poly(ethylene oxide), PEO, and poly(propylene oxide), PPO—containing different concentrations of EuBr3 were recorded and most of the observed transitions identified. The Stark components of the 7F0−4, 5D0 levels and the corresponding barycenters were calculated based on the emission lines assignment to the 5D0,1 → 7F0−4 transitions. The spectra were discussed in terms of a C2v local Eu3+ coordination. The relative intensity of the 5D0 → 7F2 hypersensitive transition was related to the electrolyte morphological changes due to increasing

AbstractA simple fluorescence microscopy technique is developed and presented to investigate heterogeneities in emission intensity and quenching responses of luminescence sensors and to measure diffusion and permeation coefficients of oxygen in polymers. Most luminescence oxygen sensors do not follow linearity of the Stern-Volmer (SV) equation due to heterogeneity of luminophore in the polymer matrix. To circumvent this limitation, inverted fluorescence microscopy is utilized in this work to investigate the SV response of the sensors at the micron scale. It was found that intensity is higher i
