摘　　要：Time-resolved photoluminescence （TRPL） was applied to investigate the transient process in GaP1-xNx （x = 0.12%） alloy. The filling, transferring and decay processes among nitrogen pairs are directly observed. The NN4 pair, either not present or only a small obscure peak under a proper excitation condition in the steady-state photoluminescence spectrum, is well resolved by TRPL.Time-resolved photoluminescence （TRPL） was applied to investigate the transient process in GaP1-xNx （x = 0.12%） alloy.
