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

In athletics, efficient screening tools are sought to curb the rising number of noncontact injuries and associated health care costs. The authors hypothesized that an injury prediction algorithm that incorporates movement screening performance, demog

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
