Abstract
Material transparent at infra red wavelengths, 3-5 and 8-14 mu m is formed of ZrN, YN, CeN, TLN, or EuN. The material can be used as a self supporting material or as a coating on substrates such as infra red transparent material e.g. Ge, ZnS, ZnSe, As2S3, As2Se3, optically transparent materials e.g. sodium glass, or reflecting surfaces such as metal surfaces, e.g. Al or silvered surfaces. For some substrates e.g. Ge a thin, e.g. 10-1,000 Angstrom bonding layer may be used to improve adhesion. Bonding layers may be Ge, Si, GexC1-x, SixC1-x (0 < x < 1). The coating may be produced by sputtering in a glow discharge chamber using Ar and N gases.
