一种荧光材料及其制备方法
摘要：
本发明公开了一种荧光材料，其化学组成通式为：aNa2O-bCaO-cAl2O3-dSiO2-eIn2O3-fEu2O3，其中a、b、c、d、e和f为各组分的摩尔分数，其取值范围分别为：13≤a≤20、5≤b≤15、7≤c≤15、40≤d≤70、1≤e≤10、0.01≤f≤5，a+b+c+d+e+f=100。以该材料中的氧化铟半导体量子点荧光发射峰强度为温度探测信号，铕离子荧光发射峰强度为参比信号，二者的荧光强度比与温度呈指数关系，计算出的温度灵敏度比当前报道的同类材料具有明显的提升，所以，该荧光材料可以用于制备荧光温度探针。
摘要（英）：

The invention discloses a fluorescent material, which has a chemical composition general formula of: aNa2O-bCaO-cAl2O3-dSiO2-eIn2O3-fEu2O3, wherein a, b, c, d, e and f are the mole fractions of each component, and the value ranges are that as the following respectively: a is greater than or equal to 13 and smaller than or equal to 20, b is greater than or equal to 5 and smaller than or equal to 15, c is greater than or equal to 7 and smaller than or equal to 15, d is greater than or equal to 40 and smaller than or equal to 70, e is greater than or equal to 1 and smaller than or equal to 10, f is greater than or equal to 0.01 and smaller than or equal to 5, and a+b+c+d+e+f=100. In the material, the indium oxide semiconductor quantum dot fluorescence emission peak intensity is a temperature detection signal, europium ion fluorescence emission peak intensity is a reference signal, and the fluorescence intensity ratio of the two and temperature show an exponential relationship, the calculated temperature sensitivity is significantly improved than that of the currently reported similar materials. Therefore, the fluorescent material can be used for preparation of fluorescence temperature probes.
