Paper Abstract

Semi-insulating CdTe:V has been revealed very interesting for photorefractive applications in the near IR region, at room temperature. Addition of Zn, in amounts of some percents, improve highly the photorefractive properties of this material and its mechanical quality. We have studied Cd1-xZnxTe:V for x = 0.01, 0.04, 0.07 and 0.10 in comparison with CdTe:V, i.e. for x = 0. Photorefractive CdZnTe:V crystals are investigated by thermal and optical spectroscopies, by spectral response of steady-state photoconductivity at various temperatures, mainly in the near infrared region. The deep levels have been characterized. The role of zinc and those of the two charge levels of vanadium, V2+and V3+, in the photorefractivity properties have been determined.
