Stimulation optique dans les sulfures de zinc et de cadmium

Abstract
The conditions for stimulability of phosphors are investigated. The requirement of sufficient energy storage is fulfilled for practically, all phosphors. The following model for stimulable phosphors is proposed : they must have special emission centers which enable the electrons to recombine rapidly with positive holes in radiative transitions. Infrared irradiation releases holes from activators ; these holes are transfered to the recombination centers. The model explains many features of stimulation and quenching of light and conductivity.
