ABSTRACT = {The amorphous calcogenide semiconductor As<sub>0.63</sub>S<sub>2.70</sub>Sb<sub>1.37</sub>Te<sub>0.30</sub> was synthesized and thin 
films based on it were obtained. XRD and optical images investigations showed the 
amorphous and homogeneous nature of the samples. The optical transmission spectrum in 
the UV-Vis range of As<sub>0.63</sub>S<sub>2.70</sub>Sb<sub>1.37</sub>Te<sub>0.30</sub> thin films shows good transparency in the spectral 
range 0.7-3.5 µm with a single absorption threshold at 2.05 eV and with refractive index in 
infrared 2.3. The irradiation of films with light leads to a parallel shift of the transmission 
spectrum to the IR range. The materials with As<sub>0.63</sub>S<sub>2.70</sub>Sb<sub>1.37</sub>Te<sub>0.30</sub> composition have high 
optical transparency have high optical transparency that make they promises for applications 
in holographic memory devices, optical amplitude and phase recorder, optical processing 
units and others. },
