Abstract
Co2+ centre in ZnTe has been proved to be an acceptor, contrary to the previous assignment, but in agreement with the general trend in the b ehaviour of the transition metal impurities in the II-VI compounds. Th e threshold of the Co2+ + hv --> Co1+ + h transition has been found in the spectrum of photoconductivity at about 1.4 eV, close to the value already reported.
