Influence of penetrating radiation on the spectral characteristics of indium selenide doped by silver and germanium

摘要

In present report the spectral and integrated photosensitivity before and after the influence of gamma-quanta in an interval of dozes 10~4-10~8 R and pulse neutrons of fluence 10~(12)-10~(14) cm~(-2) on indium selenide single crystals doped by silver and germanium atoms have been investigated The irradiation of InSe:Ag by gamma-quanta up to 10~5 R doze does not result in appreciable changes of photosensitivity of fundamental absorption and the sensitivity in short-wave region appreciably decreases. The further increase of the gamma-quanta doze up to 10~8 R changes photosensitivity only on 15-20 %.
