【Abstract】 This paper reports investigation on time-resolved luminescence （TRL） in the temperature range between 9.3～72.2K of GaP:N crystals excited by YAG:Nd laser oprating at 355nm （the third harmonic generation）. The energy and duration of the pulsed YAG Laser are typically 3.4mJ and 10 ns, respectively. The fluorescence decay of the NN₁, NN₂ lines in the photoluminescence spectra is measured with a system consisting of a transition digitizer and a multichannel analyzer.更多还原
