Influence of Ag Photodoping on Photoinduced Changes in As_2S_3 Glass Films

概要

論文の詳細を見る
The transient photoinduced optical absorption change (TOC) and the photodarkening have been studied in Ag photodoped As_2S_3 glass films. They were observed in all of the sample films which we prepared ((As_<0.4>S_<0.6>)_<100-x>Ag_x:0≦X≦24.4at.%). For the photodarkening, the degree of the change in optical-gap energy due to the light irradiation and the heat treatment decreases with the increasing of Ag content. This may be ascribed to the fact that the motion of S atoms is hindred by the Ag atoms, causing a decrease in spatial flexibility. For the TOC, the spectral distribution of the optical absorption change has a broad peak. The peak center shifts to a lower energy position with the increasing of Ag content.
