Abstract

Transparent oxyfluoride glass-ceramics (GCs) with embedded β-Na.Y.F crystals doped with Er ions were fabricated by a melt-quenching method with subsequent heat-treatment. The structural characterizations and spectroscopic techniques were performed to verify the precipitation of β-Na.Y.F crystals and partition of the Er dopant into the crystals. Bright green up-conversion (UC) emission was achieved in Er-doped glass-ceramic (Er-GC). Furthermore, the temperature-dependent visible UC behavior based on thermally coupled energy levels (TCLs) and non-thermally coupled energy levels (NTCLs) was also examined in the temperature range 298 k to 823 K with maximum relative sensitivity () of 1.1% K at 298 K for TCLs in Er-G and Er-GC samples.

摘要

透明氧氟化物玻璃陶瓷（GCs）中嵌入了掺铒离子的β-Na.Y.F 晶体，采用熔融淬火法制备，并进行后续热处理。通过结构特征和光谱技术来验证β-Na.Y.F 晶体的析出以及 Er 掺杂剂在晶体中的分布。在掺铒玻璃陶瓷（Er-GC）中实现了明亮的绿光上转换（UC）发射。此外，还在 298 K 至 823 K 的温度范围内，基于热耦合能级（TCLs）和非热耦合能级（NTCLs），研究了可见 UC 行为随温度的变化关系，在 Er-G 和 Er-GC 样品中，TCLs 的最大相对灵敏度（）在 298 K 时为 1.1% K。
