Abstract

Optical detection of magnetic resonance (ODMR) is reported for the single negative charge state, VZn -, of the isolated zinc vacancy in ZnS. Produced by 2.5 MeV electron irradiation, it is detected in a distant donor-acceptor (DA) pair luminescent band at 570 nm in which the vacancy acts as the acceptor. Excitation and emission spectral dependences of the VZn - ODMR signals are analyzed in terms of a configurational coordinate model. We conclude that the double acceptor level (VZn =/VZn -) is located ∼1.1 eV from the valence band edge and that the trigonal Jahn-Teller relaxation energy for the VZn - state is ∼0.5 eV.
