Absorption and luminescence of V (d3) in II–VI compound semiconductors

Abstract
The absorption and luminescence spectra of the V (d3) in ZnS, ZnSe, CdSe, and CdTe are presented. Values of the crystal‐field parameters Δ, B, and C are derived from the spectra and discussed. The infrared luminescence at about 5000 cm−1, characteristic for the V (d3) impurity in II–VI and III–V compound semiconductors, is shown to be due to the 4A2(F)‐4T2(F) transition.
