ZnS:Ti crystals grown by different methods are investigated at low temperatures (2 K K) by electron paramagnetic resonance (EPR) and optical spectroscopies, mainly with regard to their photoluminescence properties, including excitation and sensitisat

A Cr-related near-infrared photoluminescence (PL) band in ZnSe with a main no-phonon line at is investigated. Zeeman splitting indicates a tetragonally distorted ground state. The experimental data agree well with calculations using a spin Hamiltonia

A new near-infrared luminescence band due to internal transitions of tungsten in ZnSe crystals is described. It is characterized by a weak zero-phonon line (ZPL) at ( nm) and 40 partially strong phonon satellites which reveal the presence of quasiloc

CdS, CdSe and Cd(S,Se) crystals were grown and doped by Ti in a sublimation process. By EPR, the ground states of Ti 2+ (d 2 ) and Ti 3+ (d 1 ) are detected, indicating a substitutional incorporation as Ti Cd . For the first time, the Jahn-Teller ion

Four V-related electron-paramagnetic-resonance (EPR) spectra are observed in Bridgman-grown ZnTe doped with vanadium. Two of them are attributed to the charge states ${{\mathrm{V}}_{\mathrm{Zn}}}^{3+}({A}^{+})$ and ${{\mathrm{V}}_{\mathrm{Zn}}}^{2+}(

The PL spectrum of In-doped CdTe is known to exhibit, in many cases, a characteristic feature (the 'W line') at about 12780 cm-1 ( approximately=1.584 eV), for which there are contradictory assignments in the literature. Using bulk CdTe:In crystals w

In CdTe doped with vanadium the photoluminescence due to the 3T2(F) → 3A2(F) transition of V3+(d2) is detected. Its decay time is determined as (630±20) μs, a result comparable to the analogous emissions in various host lattices. Further emission
