Multi-component selenium rich glasses with various arsenic content have been prepared using conventional melt-quenching technique. XRD, SEM and EDX were carried out to study the structure of the prepared samples. From XRD it is found that studied samples are amorphous. DSC has been recorded which confirms that the prepared material is of glassy nature. FTIR spectra give information regarding presence of impurities in the glass. Optical parameters like α, E_g, E_u and n have been determined from the UV–Vis transmittance spectra. It has been noticed that the film transparency and optical bandgap have been increased whereas the absorption coefficient and extinction coefficient k decreased with increasing As concentration. It was found that the prepared samples obey the allowed indirect transition process. The increase in optical bandgap with As concentration has been described by Mott and Davis model. The refractive index shows ordinary dispersion behavior while it increases with As concentration.

使用常规的熔融淬火技术已经制备了具有多种砷含量的多组分富硒玻璃。用XRD，SEM和EDX对制备的样品的结构进行了研究。从XRD发现，所研究的样品是无定形的。已经记录了DSC，证实了所制备的材料是玻璃状的。FTIR光谱给出有关玻璃中杂质存在的信息。光学参数，例如α，E _g， E _u和n是从UV-Vis透射光谱确定的。已经注意到，随着As浓度的增加，膜的透明度和光学带隙增加，而吸收系数和消光系数k减小。发现制备的样品服从允许的间接过渡过程。Mott和Davis模型已经描述了随着As浓度增加的光学带隙。折射率显示出通常的色散行为，而随砷浓度的增加而增加。
