Abstract
Acoustic properties of characteristic acoustic impedance, longitudinal velocity and density for evaporated chalcogenide glass films of As-S, As2Se3 and As-S-Se systems are determined by reflection loss measurements in an acoustic transmission line composed of sapphire/chalcogenide-glass-film/water system in the UHF range. It is found that, by appropriately selecting the As/S/Se composition ratio of the evaporation source, the characteristic acoustic impedance of the evaporated chalcogenide glass film can be controlled within a range of 5.53¿9.30×106 kg m¿2s¿1.
