The luminescence of AgBr and AgBrCl crystals doped with Pr(3+) rare-earth ions was investigated in the visible and infrared spectral ranges. We measured the excitation, emission, and absorption spectra as well as the kinetic parameters over a broad temperature range. The strong influence of the silver halide composition on Pr(3+) ions spectroscopic properties was revealed. We calculated useful optical parameters for Pr:AgBr crystals by using the Judd-Ofelt approximation. Good agreement between the theoretical and the measured parameters was obtained.
研究了掺杂Pr(3+)稀土离子的AgBr和AgBrCl晶体在可见和红外光谱范围内的发光特性。我们在很宽的温度范围内测量了激发光谱、发射光谱、吸收光谱以及动力学参数。揭示了卤化银组成对Pr(3+)离子光谱性质的强烈影响。我们利用Judd-Ofelt近似计算了Pr:AgBr晶体的有用光学参数。理论参数与测量参数之间取得了良好的一致性。
