“…Also, lead to develop the glass forming area and create compositional and configurational disorder in the system and has large effect on their structural, physical and thermal properties, thus are considered as candidate materials in batteries, optics, optoelectronics, chemistry, and biology [3,[10][11][12][13][14][15][16]. Generally, the non-linear refractive index of chalcogenide glasses of Ag-doped is higher than that of the un-doped glasses because the presence of silver (transition-metal) atoms formed easily polarizable electron clouds is a evident advantage [14].…”

The effect of thermal annealing process on both structural and optical properties of amorphous As47.5Se47.5Ag5 thin films was studied. The X-ray diffraction studies exhibit that the crystallinity was improved by increasing the annealing temperature. Further, the crystallite size and the crystallinity increase whereas dislocation density and strain decrease with increase of annealing temperatures. The optical constants of the as-prepared and annealed of As47.5Se47.5Ag5 thin films were calculated using envelope method. The optical absorption data in these films were successfully describes by Tauc's relation which exhibit the indirect transitions for as-prepared sample and allowed direct transition for annealed sample above onset temperature Tc. It is evident that the energy gap E opt g decreases and the localized states Ee increases as a function annealing temperature. The dispersion of the refractive index n for these films was discussed using the single oscillator model proposed by the Wemple-DiDomenico relationship.

“…It has established that with large exposure of illumination time, the white light induces crystallization in Se-Te thin film [8]. Abd-Elrahman et al [9] studied the effect of thermal annealing on optical properties of AgAs-S thin film. Huang et al [10] reported the effective thermal parameters of chalcogenide thin films and simulation of phase-change memory.…”

This paper reports the photo-induced crystallization in glassy Ga 10 Se 78 Tl 12 thin films. The glassy nature of the bulk material was confirmed by non-isothermal differential scanning calorimetry measurements. The photo-induced crystallization in Ga 10 Se 78 Tl 12 films was done by exposing to light (using 2000 W tungsten lamp) at various illumination times under the fixed ambient temperature at 358 K. Virgin and photo-induced Ga 10 Se 78 Tl 1 thin films were characterized by X-rays diffraction, scanning electron microscopy, optical and electrical measurements. The photo-induced crystallization is associated to the change in structure of Ga 10 Se 78 Tl 12 thin films which initiated the significant change in the optical constants. The detailed examination of the optical absorption results indicated that the optical transition was indirect. The optical band gap of Ga 10 Se 78 Tl 12 thin films were decreased while the absorption and the extinction coefficients increased with the increase of illumination time. From dark conductivity results, the dark conductivities of thin films continuously heightened and the activation energy turned to be lower as increasing the illumination time. The lowering in optical band gap and activation energy might be due to the occurrence of photo crystallization with the increment of illumination time.
