Optical absorption and photoconductivity in thin films of unstable azides. Part 1.—Cuprous azide

Abstract

Thin films of CuN₃ were prepared by the solid-state reaction between thin films of alkali azides and cuprous halides. Electron diffraction studies and optical absorption measurements identify the reaction products as alkali halides and CuN₃. The spectral distribution of the photocurrent in CuN₃ thin films was measured. Optical absorption spectra and photoconductivity are interpreted in terms of an energy level diagram.
