采用熔融淬火和热处理工艺制备了高透过率的NaY_2F_7：Er ~（3+），Yb ~（3+）微晶玻璃。通过X射线衍射、透射光谱和上转换发射光谱对样品的结构、形貌和光致发光性能进行了研究。由于热处理后结晶度的提高，GC的上转换发光强度显著高于前体玻璃。探讨了Er 3+离子在热耦合能级（2 H11/2/4S 3/2）和非热耦合能级（2 H11/2/4F 9/2）下的光学测温性能。在323 K时，它们的相对灵敏度（SR）分别为1.00%K − 1和0.76%K − 1。在563 K时，最大测温误差（ΔT）分别为0.09 K和0.12 K，重复性（R）分别超过99%和98%。实验结果表明，NaY_2F_7 GC是一种优良的自校准测温材料，具有上级温度分辨率和重复性。
NaY2F7:Er3+,Yb3+glass-ceramics (GC) with high transmittance were well manufactured using a melt-quenching technique and subsequent thermal treatment. Structure, morphology and photoluminescence properties of all samples were thoroughly studied via X-ray diffraction, transmission and up-conversion emission spectrum. Due to the improved crystallinity after thermal treatment, the up-conversion emission intensity of GC was significantly higher than the precursor glass. The optical thermometry performances of Er3+ions at thermally coupled (2H11/2/4S3/2), and non-thermally coupled energy levels (2H11/2/4F9/2) were explored. Their relative sensitivities (SR) are 1.00% K−1and 0.76% K−1at 323 K, respectively. Moreover, their maximum temperature measurement errors (ΔT) are 0.09 K and 0.12 K at 563 K, with repeatability (R) exceeding 99% and 98%, respectively. All of the findings suggest that NaY2F7GC are excellent self-calibration temperature measuring materials, with superior temperature resolution and repeatability.
