摘要：

The transition metal ions titanium and vanadium in CdTe are studied by optical absorption, electron paramagnetic resonance (EPR), magnetic circular dichroism (MCD) and optically detected magnetic resonance (ODMR) spectroscopy. Titanium is observed in two different charge states, Ti2+ (3d(2)) and Ti3+ (3d(1)) by EPR. Absorption measurements however show only the (3)A(2)-->T-3(1)(P-3) and (3)A(2)-->(1)E(D-1) infernal transitions of Ti2+. This assignment is confirmed by MCD and ODMR measurements. For vanadium-doped CdTe only the V3+ charge state is observed in EPR. In absorption two pronounced absorption bands are seen which are attributed to internal transitions of V3+.
