Abstract:

Nanocrystalline films and precipitates of copper(I) selenide were prepared by chemical depositions from aqueous solutions at 333 K. Cubic structure of Cu2-x Se (space group Fm-3m) with crystal lattice constant 5.693 with inclusion of cubic phase of cuprous oxide Cu2O (space group 224) was revealed by X-ray diffraction of the precipitates. Freshly deposited films and precipitates were shown to consist of polyhedral crystallites with characteristic size of 50-400 and 80-500 nm, respectively. The found formula composition of hydrochemically deposited films and precipitates corresponds to compounds Cu1.54Se and Cu1.84Se, respectively. Elemental analysis data for Cu1.54Se films thermally treated in air atmosphere showed their stability to heating up to 220-230A degrees C.
