In this paper we have reported the observation of visible photoluminescence (PL) and cathodoluminescence (CU) of Pr implanted in GaN. The implanted samples were given isochronal thermal annealing treatments at a temperature of 1100°C in NH{sub}3, N{sub}2, Ar{sub}2, and in forming gas N{sub}2+H{sub}2, at atmospheric pressure to recover implantation damages and activate the rare earth ions. The sharp characteristic emission lines corresponding to Pr{sup}(3+) intra-4f{sup}n -shell transitions are resolved in the spectral range from 350 am to 1150nm, and observed over the temperature range of 12 K-335 K. The PL and CL decay kinetics measurement was performed for 3{sup left}P{sub}1, 3{sup left}P{sub}0 and 1{sup left}D{sub}2 levels.
