Abstract
A strong, optically detected magnetic-resonance (ODMR) sign at g=1.99 is observed on the internal 3T2 to 3A2 emission of V3+. The ODMR excitation spectrum is identical with the emission spectrum. From the analysis of the experimental data it is nevertheless concluded that the spin resonance does not arise from the V but is due to shallow S donors present in the sample. A model accounting for the spin-dependent electron-transfer mechanism is suggested. An unidentified photoluminescence emission centered at 1.35 eV with an isotropic g=2.06 ODMR line is also observed.
