英文摘要	Based on the results of the temperature-dependent photoluminescence (pl) measurements, the broad pl emission in the phase-separated ganp alloys with p compositions of 0.03, 0.07, and 0.15 has investigated. the broad pl peaks at 2.18, 2.12 and 1.83 ev are assigned to be an emission from the optical transitions from several trap levels, possibly the iso-electronic trap levels related to nitrogen. with the increasing p composition (from 0.03 to 0.15), these iso-electronic trap levels are shown to become resonant with the conduction band of the alloy and thus optically inactive, leading to the apparent red shift (80-160mev) of the pl peak energy and the trend of the red shift is strengthened. no pl emission peak is observed from the gan-rich ganp region, suggesting that the photogenerated carriers in the gan-rich ganp region may recombine with each other via non-radiation transitions.
