Abstract

The spectral emission of GaP:S in the range 1.5- 2.1eV (800-600nm) has been studied by cathodoluminescence in the scanning electron microscope and by photoluminescence. In as-grown samples the spectra show two bands centered at about 700-730 and 800nm. Annealing the sample above 900K enhances the band of 700nm and causes the occurence of a band centered at 610-620nm. The conditions under which each band is prominent in the luminescence spectrum are analyzed and discussed.
