Abstract:

A series of 4-dihydroquinolinone derivatives were fully optimized by density functional theory (DFT), Hartree-Fock (HF) and Configuration Interaction Singlet (CIS) approaches. Absorption spectra, emission spectra and two-photon absorption cross sections were calculated by using time-dependent density functional theory and few-state model. Calculations were performed in the presence of solvent by using Conductor polarizable continuum model (CPCM). The molecular geometries, absorption spectra, emission spectra were in good agreement well with those experiment values. The absorption and emission

Abstract:

Optical spectroscopic properties of Er3+-doped alkaline-earth metal modified fluoropho sphate glasses have been investigated experimentally for developing broadband fiber and planar amplifiers. The results show a strong correlation between the alkaline-earth metal content and the spectroscopic parameters such as absorption and emission cross sections, full widths at half-maximum and Judd-Ofelt intensity parameters. It is found that strontium ions could have more influences on the Judd-Ofelt intensity parameters and the absorption and emission cross sections than other alkaline-earth metal ions

Abstract:

We investigate the effects of short range correlations on nucleon emission in peripheral relativistic heavy ion collisions, following an idea originally proposed by Feshbach and Zabek. Expressions for one- and two-nucleon emission cross sections are derived and calculations for typical heavy ion systems are performed. We show that momentum conservation in the phonon absorption process leads to pronounced ridges in the quadruple-differential cross section for two-nucleon emission. We suggest that the presence of such ridges in future exclusive experiments should be considered as a signature of

Abstract:

When treating the absorption of light, it is instructive to focus on the absorption coefficient related to the probability of photons to survive while traversing a layer of material. From the point of view of particles doing the absorption, however, the elementary interaction of the particle with the photon is best described by the corresponding cross section. We revisit curvature radiation in order to find the absorption cross section for this process, making use of the Einstein coefficients and their relations with spontaneous and stimulated emission and true absorption. We derive the cross

The experimental lifetimes for five excited states have been compared to the theoretical values, calculated using Judd–Ofelt theory, allowing for the determination of the multiphonon relaxation rates (WnR) of the respective states.

It was found that DPP-based compounds are very weakly fluorescent in THF solution, but their intensities are increased by almost 29, 9, and 24 times in water/THF (v/v 90 %) mixtures, respectively, in which they exhibit a strongly enhanced red fluorescence. The result indicates that the intramolecular vibration and rotation of these dyes is considerably res

Abstract:

Ho3+:Tm3+:BaY2F8(Ho:Tm:BYF) laser crystal was grown by Czochralski method. The technical parameters as follows: the seeding temperature is 955°C; the pulling rate is 0.5mm/h; the rotation rate is 5rad/min; the cooling rate is 15°C/h; the period of growth is 6d. According to the spectra of crystal sample, the strongest absorption peak exists at 781nm, and the absorption cross section is 6.16×10-21cm2. While the strongest emission peak exists at 2056nm with the FWHM of 38nm, and the emission cross section is 4.05×10-21cm2, and the emission mechanism at 2056nm was analyzed based on energy level d

Abstract. Improved line positions and intensities have been generated for the 7.6 µm spectral region of nitric acid. They were obtained relying on a recent reinvestigation of the nitric acid band system at 7.6 µm and comparisons of HNO3 volume mixing ratio profiles retrieved from the Michelson Interferometer for Passive Atmospheric Sounding (MIPAS) limb emission radiances in the 11 and 7.6 µm domains. This has led to an improved database called MIPAS-2015. Comparisons with available laboratory information (individual line intensities, integrated absorption cross sections, and absorption cross

Abstract:

The OI [Formula: see text] emission cross section and the absorption cross section of O2 were investigated near the threshold for neutral dissociation into the OI [Formula: see text] state with a very narrow bandwidth (0.9 meV) of the exciting radiation. The fine-structure components of vibrational levels were resolved for the first time in the emission cross section. A certain degree of selectivity in the population of fine-structure components was observed.

Abstract:

Glasses having compositions 20B2O3.(79.5-x)Bi2O3.xSiO2(10 ≤ x ≤ 40) doped with 0.5 mol% of Sm3+ions were prepared by melt quench technique. The amorphous nature of the glasses was confirmed by X-ray diffraction studies. The spectroscopic properties of Sm3+ions in bismuth borosilicate glasses as a function of bismuth oxide were investigated using optical absorption and fluorescence spectra. The Judd-Ofelt theory has been employed to calculate transitions probability from the data of absorption cross-section of several f-f transitions. The intensity parameters Ω2is related to the symmetry of gla
