Donor-acceptor nature of the blue self-activated and the copper green emissions in ZnS crystals

Abstract Optically detected magnetic resonance experiments show that the blue self-activated luminescence is due to a recombination of an electron on an isolated donor and a hole on an A-centre. Similar experiments on crystals containing copper have shown that the Cu-green emission also involves an isolated donor. Although the acceptor has not been identified it is confirmed that the copper green luminescence is donor-acceptor in nature.
