Abstract

The paper studies the photoinduced structural changes in the optical properties of annealed films prepared from As2S1.5Se1.5Gex glasses. The results are discussed in terms of the compositional dependences of the density, compactness and average atomic volume of the parent glasses. The composition of the system which is most suitable for media for optical recording of information is identified..
