Abstract

The ErF-doped oxyfluoride phospho-tellurite glasses in the (40-x) TeO-10PO-45 (BaF-ZnF) -5NaO-xErF system (where x = 0.25, 0.50, 0.75, 1.00, and 1.25 mol%) have been prepared by the conventional melt-quenching method. The effect of erbium trifluoride addition on thermal, structure, and spectroscopic properties of oxyfluoride phospho-tellurite precursor glass was studied by differential scanning calorimetry (DSC), Fourier-transform infrared (FTIR), and Raman spectroscopy as well as emission measurements, respectively. The DSC curves were used to investigate characteristic temperatures and thermal stability of the precursor glass doped with varying content of ErF. FTIR and Raman spectra were introduced to characterize the evolution of structure and phonon energy of the glasses. It was found that the addition of ErF up to 1.25 mol% into the chemical composition of phospho-tellurite precursor glass enhanced 2.7 µm emission and upconversion. By controlled heat-treatment process of the host glass doped with the highest content of erbium trifluoride (1.25 mol%), transparent erbium-doped phospho-tellurite glass-ceramic (GC) was obtained. X-ray diffraction analysis confirmed the presence of BaF nanocrystals with the average 16 nm diameter in a glass matrix. Moreover, MIR, NIR, and UC emissions of the glass-ceramic were discussed in detail and compared to the spectroscopic properties of the glass doped with 1.25 mol% of ErF (the base glass).

摘要

采用传统的熔体淬火法制备了(40-x)TeO-10PO-45(BaF-ZnF)-5NaO-xErF体系（其中x = 0.25、0.50、0.75、1.00和1.25 mol%）的掺铒氧氟磷碲酸盐玻璃。分别通过差示扫描量热法(DSC)、傅里叶变换红外光谱(FTIR)、拉曼光谱以及发射测量研究了三氟化铒添加量对氧氟磷碲酸盐前驱体玻璃的热性能、结构和光谱性质的影响。利用DSC曲线研究了不同ErF含量掺杂的前驱体玻璃的特征温度和热稳定性。引入FTIR和拉曼光谱来表征玻璃的结构演变和声子能量。结果发现，在磷碲酸盐前驱体玻璃的化学组成中添加高达1.25 mol%的ErF可增强2.7 µm发射和上转换。通过对掺杂最高含量三氟化铒(1.25 mol%)的主体玻璃进行可控热处理，获得了透明的掺铒磷碲酸盐玻璃陶瓷(GC)。X射线衍射分析证实了在玻璃基体中存在平均直径为16 nm的BaF纳米晶体。此外，详细讨论了玻璃陶瓷的中红外、近红外和上转换发射，并与掺杂1.25 mol% ErF的玻璃（基础玻璃）的光谱性质进行了比较。
