In paper is presented an idea allowed to explain empirically found optically induced phenomena - mid-gap absorption, fatique effect, ESR signal and mutual correlations of these phenomena. We assume that the above mentioned effects are closely related to photoluminescence. We suppose that photoluminescence creates conditions for the formation of photoinduced short-living traps in the center of the band gap, in region of photoluminescence spectrum. The starting point of our considerations is barrier-cluster-heating model..
