我们给出了重要的倍半氧化物激光材料Yb：Lu2O3的新的高分辨率吸收数据，光谱范围为880-1020 nm，光谱范围为8-300℃，零声子区为960-990 nm，温度为8-300℃。我们首次实验观察到了C3I(0，1)-(1，3)跃迁，它位于8℃下的880.7 nm处。对C2和C3izero谱线数据的详细拟合和作图表明，谱线宽度从100℃以下以电子为主演变为100℃以上以热过程为主。我们还发现了80-100℃之间改变局域配位环境的“软”相变的证据。
We present new high-resolution absorption data for the important sesquioxide laser material Yb:Lu2O3for the spectral range of 880–1020 nm, at various temperatures between 8 and 300 K, and for the zero-phonon region from 960 to 990 nm, at temperatures from 8 to 300 K. We have experimentally observed the C3i(0,1)–(1,3) transition for the first time, located at 880.7 nm at 8 K. Based on high confidence fitting functions to the experimental data, we provide the first complete compilation of all observed electronic and electronic–vibrational transitions. Detailed fitting and plots of the C2and C3izero-line data show an evolution of the linewidth from being predominantly electronic below about 100 K to being dominated by thermal processes above 100 K. We have also found evidence for a “soft” phase transition between 80 and 100 K that changes the local coordination environment.
