摘要
使用调QYAG:Nd激光器的三倍频脉冲光(λ=355nm)激发GaP:N晶体,测量了9.3～72.2K温度范围内样品的光致发光,研究了在10～250ns不同延迟时间的分辨光谱;借助瞬态谱仪和多道分析器测量了PL谱中NN_1、NN_2荧光强度衰减曲线。
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 NN_1, NN_2 lines in the photoluminescence spectra is measured with a system consisting of a transition digitizer and a multichannel analyzer.
