Results of the high pressure low-temperature luminescence measurements of ZnTe:Cr2+ crystals in a diamond-anvil cell are reported. The luminescence spectra associated with the 5E? 5T2 transitions are split into three bands which exhibit quite different pressure coefficients from about 8 to 12?cm?1. The different values of the pressure coefficients are well explained by the Jahn?Teller effect and pressure-dependent spin?orbit interaction with second-order correction, associated with pressure-dependent admixture of the Te ligand wavefunction to the d-type wavefunction of the Cr2+ ion.
