A series of optical thermometers based on Eu³⁺/Tb³⁺ doped Y₃Ga₅O₁₂ with self-excited GaO₆ group phosphors were designed through controllable energy transfer and local crystal field perturbation simulated using the density-functional theory approach and related structures. Color-tunable properties of the phosphors could be achieved through controllable energy transfer. In addition, the thermometers exhibited superb temperature sensitive properties. Over the entire temperature range (298.15–598.15 K), maximum values of the absolute sensitivity and relative sensitivity are 0.028 K⁻¹ and 7.03 %K⁻¹, respectively. Meanwhile, the thermometer has outstanding resolution (ΔT = 0.0043 K) and repeatability (98.37%).

通过可控能量转移和局部晶体场微扰，利用密度泛函理论方法和相关理论，设计了一系列基于Eu ³⁺ /Tb ³⁺掺杂Y ₃ Ga ₅ O ₁₂和自激GaO ₆族荧光粉的光学温度计。结构。荧光粉的颜色可调特性可以通过可控的能量转移来实现。此外，温度计表现出极好的温度敏感特性。在整个温度范围 (298.15–598.15 K) 内，绝对灵敏度和相对灵敏度的最大值分别为 0.028 K ^-1和 7.03 %K ^-1， 分别。同时，该温度计具有出色的分辨率（ΔT = 0.0043 K）和重复性（98.37%）。
