Optical photoinduced absorption in As2S3 thin films doped with rare-earth ions

Authors:

Iovu, Mihail; Cojocaru, Ion; Colomeico, Eduard

Summary:

In the present paper we have focused our study on relaxation of photodarkening in α-As S doped with rare-earth ions (Dy , Pr , Nd ). It was shown that the degree of photo- structural transformation depends on the species and concentration of rare-earth ions. The relaxation process of photodarkening is described by a stretched exponential function with the dispersion parameter 0
