The optical properties of Bridgman method grown Ga2SeS crystals have been investigated by means of room-temperature transmittance and reflectance spectral analysis. The optical data have revealed direct and indirect allowed transition band gaps of 2.49 and 2.10 eV, respectively. The room-temperature refractive index, which was calculated from the reflectance and transmittance data, allowed the identification of the dispersion and oscillator energies, static dielectric constant and static refractive index as 20.93 eV and 4.01 eV, 6.21 and 2.49, respectively.

Energy band gap and oscillator parameters of Ga4Se3S single crystals Qasrawi, A. F.; Hasanlı, Nızamı (Elsevier BV, 2007-06-01) The optical properties of the Bridgman method grown Ga4Se3S crystals have been investigated by means of room temperature, transmittance and reflectance spectral analysis. The optical data have revealed an indirect allowed transition band gap of 2.08 eV. The room temperature refractive index, which was calculated from the reflectance and transmittance data, allowed the identification of the dispersion and oscillator energies, static dielectric constant and static refractive index as 21.08 and 3.85 eV, 6.48 a...
Optoelectrochemical properties of the copolymer of 2,5-di(4-methylthiophen-2-yl)-1-(4-nitrophenyl)-1H-pyrrole monomer with 3,4-ethylenedioxythiophene AK, Metin; Tanyeli, Cihangir; Akhmedo, Dris M.; Toppare, Levent Kamil (Elsevier BV, 2008-04-30) Copolymer of 2,5-di(4-methylthiophen-2-yl)-1-(4-nitrophenyl)-1H-pyrrole (MTNP) with 3,4-ethylene dioxythiophene (EDOT) was electro-chemically synthesized and characterized via cyclic voltammetry, Fourier Transform Infrared spectroscopy, Scanning Electron Microscopy, conductivity measurements. Spectroelectrochemical investigations showed that resulting copolymer film has distinct electrochromic properties. It has five different colors (dark purple, red, light grey, green, blue). At the neutral state m due to...
Optical properties of (Ga2Se3)(0.)(75) - (Ga2S3)(0.)(25) single crystals by spectroscopic ellipsometry Işık, Mehmet; Hasanlı, Nızamı; Gasanova, L. (Elsevier BV, 2019-05-01) Structural and optical properties of 75 mol % Ga2Se3 - 25 mol % Ga2S3 system of single crystals were investigated by experimental techniques of x-ray diffraction (XRD), energy dispersive spectroscopy, Raman spectroscopy and ellipsometry. XRD pattern indicated that the studied compound has crystalline nature with cubic structure. Vibrational modes in the crystal were revealed using Raman spectroscopy experiments in the 90-450 cm(-1) frequency range and nine modes were observed in the spectrum. Ellipsometry m...
Phonon dispersions and elastic constants of disordered Pd-Ni alloys Kart, SO; Tomak, Mehmet; Cagin, T (Elsevier BV, 2005-01-31) Phonon frequencies of Pd-Ni alloys are calculated by molecular dynamics (MD) simulation. Lattice dynamical properties computed from Sutton-Chen (SC) and quantum Sutton-Chen (Q-SC) potentials as a function of temperature are compared with each other. We present all interatomic force constants up to the 8th nearest-neighbor shell obtained by using the calculated potential. Elastic constants evaluated by two methods are consistent with each other. The transferability of the potential is also tested. The result...
Photo-stimulated luminescence of calcium co-doped BaFBr : Eu2+ x-ray storage phosphors SCHLAPP, M; Bulur, Enver; VON SEGGERN, H (IOP Publishing, 2003-01-21) The influence of calcium co-doping on the optical properties of the x-ray storage phosphor BaFBr: Eu2+, is determined by photo- stimulated luminescence techniques. It is found that the incorporation of calcium into the lattice results in a broadening of the photo- stimulation peak due to a calcium induced FA(Br, Ca2+)-centre with stimulation maxima at 540 and 680 nm. The optical cross-sections for the photo- stimulated process are determined by utilizing stimulation light with linearly increasing intensity....
