| Abstract: | The visible and the near-infrared electroluminescence spectra of GaP: N light-emitting diodes (LEDs) were measured before and after degradation. The 650 um luminescence band was obserued in the spectra after degradation. The luminescence intensities of 590 um and 1260 um bands are strorger after degradation than before degradation. The deep levels related to the phosphorus and nitrogen due to degradation strongly influence the luminescence properties of GaP: N LED. |
