我们展示了亚微米级 LiNbO3:Er3+/Yb3+ 颗粒在 12 至 180 摄氏度范围内的绿色上转换发光的温度依赖性。结果表明，LiNbO3:Er3+/Yb3+ 表现出非常高的灵敏度（生理温度下 S = 0.007/摄氏度，350 摄氏度下 S = 0.014/摄氏度最大值） C）超过了之前发现的基于 Er3+/Yb3+ 发光的其他材料，表明 LiNbO3:Er3+/Yb3+ 是一种适合通过荧光强度比技术进行光学温度传感的探针。这种高灵敏度可以使用该主体中 Er3+ 离子的固有光谱参数来解释。 (C) 2011 日本应用物理学会
We present the temperature dependence of the green up-converted luminescence in submicron-sized LiNbO3:Er3+/Yb3+ particles in the range between 12 and 180 degrees C. It is shown that LiNbO3:Er3+/Yb3+ exhibits a very high sensitivity (S = 0.007/degrees C at physiological temperature and a maximum value of S = 0.014/degrees C at 350 degrees C) that surpasses those previously found for other materials based on Er3+/Yb3+ luminescence, indicating that LiNbO3: Er3+/Yb3+ is a suitable probe for optical temperature sensing through the fluorescence intensity ratio technique. This high sensitivity can be explained using the intrinsic spectroscopic parameters of Er3+ ions in this host. (C) 2011 The Japan Society of Applied Physics
