The luminescence of silver bromide crystals doped with praseodymium and erbium ions was investigated over the visible and near-infrared spectral regions. The emission, excitation, and absorption spectra, as well as kinetic parameters, were measured over a broad temperature range. The Judd-Ofelt analysis was used to calculate transition rates, branching ratios, and luminescence quantum efficiencies of rare-earth doped crystals. Good agreement between theoretical and experimental results was obtained.
研究了掺有镨和铒离子的溴化银晶体在可见光和近红外光谱区域的发光特性。在较宽的温度范围内测量了发射光谱、激发光谱、吸收光谱以及动力学参数。采用Judd-Ofelt分析方法计算了稀土掺杂晶体的跃迁速率、分支比和发光量子效率。理论结果与实验结果吻合良好。
