Summary:Ternary Sii5Ge (Ga)5Te8o, Si1g.7Te78.7Seis, Siig.2Te78.8Se4, and Ge,gTe 72Se g telluride glasses were synthesized. Electrical, acoustic, acoustooptical properties, and the dispersion of optical transmittance of these films were studied in a wide range of temperatures and frequencies. Comparative analysis of the results obtained is performed. Possible mechanisms of the observed phenomena are discussed. It is shown that Gei9Te72Seg alloy is quite competitive with Si2oTe8o alloy for the fabrication of highly efficient acoustooptical devices with a wide range of applications in the medium IR spectral region (2-12 pm).
