The near-infrared electroluminescence spectra of GaP pure green (PG) light-emitting diodes (LEDs) were studied at room temperature (300K) and liquid nitrogen temperature (77K). Many overlapping broad emission bands were observed in the luminescence spectra. The spectra were fitted with Gaussian lineshapes and can be decomposed into six Gaussian peaks. Finally the origins of the deep level luminescence bands in the GaP PG LEDs and the influence of deep levels on the luminescence intensities of the LEDs were discussed.
