Bridgman-grown crystals, doped with Ti, were investigated by using near-infrared optical spectroscopic and electron paramagnetic resonance techniques. The luminescence spectra of Ti centers in Ti-doped Cd0.85Zn0.15Te reflected a 3T2(F)  3A2(F) transition of Ti2+, that was centered at 2600/cm, and a 2T2(D)  2E(D) emission of Ti3+ around 3200/cm. The excitation spectrum of the Ti2+ luminescence exhibited 3 excitation bands, and near-gap levels.
