Light Emission from Quantum Well Structures Containing ZnS, ZnSe, and Related Alloys

Abstract
Properties of blue and blue-green laser diodes with ZnCdSe single- and multiple-quantum-well active regions are discussed. Blue, blue-green, and green light emitting diodes which employ ZnCdSe or ZnSTeSe as the active region of double heterostructure devices have also been prepared and tested. Properties of ZnS-ZnSSe and ZnS-ZnCdS quantum well structures are also reported. These structures emit intense photoluminescence in the ultraviolet spectral region.
