Abstract
The theory of new type detectors based on the ''quenching'' of seconda ry emission in direct-gap semiconductors (lines of Raman light scatter ing due to interaction between free and bound excitons in the crystal, and also bands of ''edge'' radiation) caused by IR or submillimeter r adiation is proposed. The results obtained are confirmed by the experi ment performed for CdS crystal excited by ultraviolet radiation of mer cury lamp, at liquid helium temperature.
