Abstract

The photoluminescence and optical properties of Mg x Zn1−xTe alloys have been studied in the composition range 0<x<0.48. The results are discussed taking into account the formation of band tails due to the alloying effect or random distribution of impurities. The role of residual defects in magnesium-rich alloys is emphasized. On the other hand, a preliminary investigation showed that it is possible to incorporate lithium by high-temperature diffusion in Mg x Zn1−xTe alloys without altering the magnitude or the homogeneity of the magnesium concentration. Evidence is obtained for an increased quantum efficiency after lithium doping.
