In this paper the authors have reported the observation of visible photoluminescence (PL) and cathodoluminescence (CL) 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 nm to 1150 nm, and observed over the temperature range of 12 K--335 K. The PL and CL decay kinetics measurement was performed for {sup 3}P{sub 1}, {sup 3}P{sub 0} and {sup 1}D{sub 2} levels.
