Abstract
The 5E(D) --> 5T2(D) photoluminescence of V+(d4) is studied for ZnS an d ZnSe at T = 4.2 K. ZnSe displays a no-phonon peak at 3640 cm-1, ZnS a triplet near 3914 cm-1. The vibronic structure of the emission spect ra indicates combined spin-orbit and Jahn-Teller interactions. Excitat ion spectra are recorded and described by a Tanabe-Sugano calculation in the lower energy range while charge-transfer processes occur at hig her energies.
