Abstract
Thermal evaporation, flash evaporation and rf-sputtering techniques were applied to the preparation of amorphous films of superionic conducting glasses in the systems AgIAg 2MoO 4 and AgIAg 2OB 2O 3. The flash-evaporated films were amorphous and showed very high conductivities, about 2 × 10 −2 S/ cm for the AgIAg 2MoO 4 and about 5 × 10 −3 S/ cm for the AgIAg 2OB 2O 3 at room temperature, and gave a Ag + transport number of unity. The thermal evaporation method produced crystalline-phase included films. The rf-sputtered films were amorphous by X-ray diffraction and the transport number of Ag + ions was smaller than unity (about 0.9). Thus flash evaporation was concluded to be the most suitable method for preparing amorphous films of superionic conducting glasses.
