AB Cathodoluminescence (CL) from untreated as well as heat-treated GaP:Te:Mn samples has been investigated. Spectra of untreated samples present two emission bands that peak at 585 and 730 nm. The CL image shows bright spots associated with dislocations, as well as doping striations. The red band (730 nm) is higher at these bright spots. Heat treatments enhance the red-band emission, while the bright spot contrast remains. Time-resolved photoluminescence indicates that the red band is due to excitons bound to complexes.
