THE RELAXATION OF PHOTODARKENING IN Sn DOPED AMORPHOUS As2Se3 FILMS
Photodarkening relaxation under light exposure of a-As2Se3 amorphous films doped with 0.5-5.0 at.% Sn was studied for its dependence on the concentration of impurities and thermal treatment. Both factors reduce photodarkening with the degree of reduction dependent on the concentration of impurity. The relaxation process may be described by a stretched exponential with the dispersion parameter 0...
متن کاملFirst- and Second-Order Bragg Gratings in Single-Mode Planar Waveguides of Chalcogenide Glasses
Firstand second-order Bragg reflectors at telecommunication wavelength (1.5 m) were fabricated in single-mode monolayer (As2S3) and multilayer (As-S-Se/As-S) chalcogenide glass (ChG) planar waveguides with near bandgap illumination using an interferometric technique. Reflectivities as high as 90% near 1555 nm, and index modulations up to 3 10 4 were achieved. The volume photodarkening effect is...
متن کاملMicrostructure, mechanical and thermal properties of chalcogenide glasses and glass-ceramics based on Se-As-Ge system nucleated by Sn
In particular, chalcogenide glasses and glass-ceramics are new materials that exhibit good transparency in infrared region (0.8-12µm). We can overcome the main weakness of these glasses by improving the hardness through controlling crystallization. In this paper, we report results of a study on chalcogenide glasses in the ternary system of As-Se-Ge with nominal composition of Snx (Se...
متن کاملCrystallization Kinetics of Chalcogenide Glasses
Chalcogenide glasses are disordered non crystalline materials which have pronounced tendency their atoms to link together to form link chain. Chalcogenide glasses can be obtained by mixing the chalcogen elements, viz, S, Se and Te with elements of the periodic table such as Ga, In, Si, Ge, Sn, As, Sb and Bi, Ag, Cd, Zn etc. In these glasses, short-range inter-atomic forces are predominantly cov...
متن کاملFabrication and Structural Characterization of Se-Ge Chalcogenide Glasses by Means of Melt Quenching Technique
The structural and optical characterization of Se-Ge alloys during melt quenching technique was the goal of this study. In this regards, five different samples of Se100-xGex (x= 10, 20, 30, 40, 50) were prepared by conventional melt quenching in quartz ampoule. The produced samples were characterized using X-ray diffraction (XRD), scanning electron microscopy (SEM), differential scanning calori...
