Abstract In a comprehensive and novel approach, a diverse set of five functional models of temperature sensing were established for erbium-doped oxyfluorotellurite glass systems using temperature dependences of emission spectra and luminescence dynamics in the range from RT to up to 675 K. Maximum relative sensitivity at 300 K was established at 1.52%K−1 for the model based on thermally coupled levels and at 1.92%K−1 at 675 K utilizing the green-to-red ratio. To confirm usefulness of the models established for the considered glasses, material and spectroscopic analyses were performed. Differential thermal analysis yielded favorable results in terms of glass thermal stability, further improving with increase of dopant concentration. Radiative transition analysis was performed, along with calculation of absorption, emission and effective emission cross sections, yielding information on the lasing performance of the material. It was found that TZPN:Er is a promising material for temperature sensing and optical amplification in the C and L telecom bands.

摘要 在一种全面而新颖的方法中，使用从 RT 到高达 675 K 范围内的发射光谱和发光动力学的温度依赖性，为掺铒氧氟碲酸盐玻璃系统建立了一组由五个不同的温度传感功能模型。最大相对灵敏度对于基于热耦合水平的模型，在 300 K 时为 1.52%K-1，在 675 K 时使用绿红比为 1.92%K-1。为了确认为所考虑的玻璃建立的模型的有用性，进行了材料和光谱分析。差热分析在玻璃热稳定性方面产生了良好的结果，并随着掺杂浓度的增加而进一步提高。进行了辐射跃迁分析，以及吸收的计算，发射和有效发射截面，产生有关材料激光性能的信息。结果表明，TZPN:Er 是一种很有前途的材料，可用于 C 和 L 电信波段的温度传感和光放大。
