Abstract
Luminescent emission from zinc‐cadmium sulfide crystals with graded composition has been investigated. The edge emission spectrum was found to vary linearly with electric field applied parallel to the composition gradient. Possible mechanisms are evaluated, and it is concluded that positive hole transport between regions with different band gaps is responsible for the spectral shift. The effect can be used to determine the product of minority carrier lifetime and mobility.Keywords
