Radiation properties of zinc diphosphide and their influence on infrared absorption

Studying of simple and complex defects in zinc diphosphide after ionizing irradiation has been carried out. ZnP 2 crystals of (alpha) - and (beta) -modification have been irradiated by (gamma) -rays of Co 60 , electrons and reactor's neutrons. Electrical and optical characteristics of initial, irradiated at different temperatures and annealed samples have been measured. From the analysis of experimental and literary dates it is clear that phosphorous chains in zinc diphosphide possess low radiation resistance and main optically active centers are induced by fast particles to phosphorous quasi-molecules.
