Abstract
A Cr-related near-infrared photoluminescence (PL) band in ZnSe with a main nophonon line at 10 702.2 cm−1 is investigated. Zeeman splitting indicates a tetragonally distorted ground state. The experimental data agree well with calculations using a spin Hamiltonian with parameters obtained from the 5T2(D) ground state of ZnSe: Cr2+(d4). This contradicts a former
assignment of the PL band to a 4T1/ G→6A1(S) emission of ZnSe: Cr+(d5). Crystal field calculations demonstrate that the observed no-phonon lines and the corresponding luminescence band can reasonably be interpreted in terms of a 3T1(H)→5T2(D) transition within the d4
configuration of Cr2+. Furthermore, the influence of unmodulated supplementary irradiation on
transmission and PL excitation spectra is discussed.
