ODMR study of the recombination processes in GaP:O

Abstract
The local symmetry and transient properties of the ODMR signals related to the oxygen centre in GaP have been studied in detail. The associated impurity centre was observed to have an orthorhombic or lower symmetry and one order of magnitude difference of lifetimes between the 0.841 eV emission and the ODMR signals of this emission were found. Possible recombination processes involving the Jahn-Teller effect are discussed.
