Abstract:

Recent studies on the growth of ZnO nanostructures and their optical properties were reviewed. Using different methods, a variety of ZnO nanostructures, including quantum dots nanotowers, nanotubes, nanorods, nanowires, and nanosheets, displaying zero, one, and two dimensions, have been synthesized. The growth of ZnO low-dimensional nanostructures has been demonstrated. Their optical properties have been studied by means of room-temperature photoluminescence spectra, low-temperature photoluminescence spectra, temperature-dependent photoluminescence spectra, and pressure-dependent photoluminesc

Abstract:

InAs/GaAs quantum dots structures are grown by meta-organic chemical vapor deposition. The effects of growth temperatures on the structural and optical properties of quantum dots are investigated by the atomic force microscopy and photoluminescence. An areal density of 9.3×109cm2 and a strongly enhanced photoluminescence intensity are obtained at the temperature of 505°C, furthermore, the low and high growth temperature tend to form coalescent islands and decrease the intensity of photoluminescence spectra.

Photoluminescent nematic liquid crystals have been an attractive research target for decades, because of their potential applications in optoelectrical devices. Integration of luminescent motifs into cyclic structures is a promising approach to induce low-ordered liquid-crystalline phases, even though relatively large and rigid luminophores are used as emitters. Here, we demonstrate a 1,6-diphenylpyrene-based, unsymmetric cyclophane showing a stable nematic phase at room temperature and exhibiting strong photoluminescence from the condensed state.

Abstract:

This study examines how the variation of temperature affects the photoluminescence properties of porous silicon, offering insights into surface, defects, and carrier dynamics interactions. Porous layers are obtained using an electrochemical method, revealing two notable photoluminescence emission peaks. The study suggests two different non-radiative recombination processes based on intensity changes with temperature. Surface conditions contribute to the thermal quenching of the photoluminescence at low temperatures (10–60 K), while non-radiative recombination is linked to the thermal escape of

Abstract:

The low-temperature annealing of porous silicon (PS) has been studied in ambient air and vacuum. After air-annealed samples were again stored in air for a period of time, their luminescence exhibited improved stability in comparison to fresh samples. But their luminescence intensity is much weaker than that of fresh samples, and their peak position moves to shorter wavelengths. A stoichiometric oxide SiO2 can easily be formed on PS surfaces if the annealing is performed in vacuum. The SiO2 layer prevents nc-Si from further oxidation and guarantees the luminescence intensity and that peak posit

The synthesis of ZnO:Eu3+ nanoflowers by a low-temperature hydrothermal route is described. Characterization of the materials was performed by ESEM, XRD and FTIR spectra. The 355 nm excited photoluminescence spectra at 10 K do not indicate the presence of Eu2+ or the ZnO defect states which give rise to green or red broadband emission. Excitation into the ZnO conduction band at low temperature does not give emission from Eu3+. Selective excitation of the Eu3+ emission shows that Eu3+ ions occupy a variety of different sites, of which one of them is similar to Eu3+ in C-type Eu2O3.
