 摘要:以柠檬酸为燃烧剂,采用柠檬酸凝胶法制备了Er,Tm:Yb3Al5O12(Er,Tm:YbAG)纳米粉体。其最佳的制备工艺条件为:Er3+和Tm3+的掺杂摩尔浓度分别为2%和1%,柠檬酸与金属硝酸盐原子总数的摩尔比为1.7:1,煅烧温度和时间分别为950 ℃和2 h。制备的粉体颗粒为规则球形,粒径均匀、分散性好,平均粒径约为45 nm。研究了样品的发光性能,结果表明:2%Er,1%Tm:YbAG样品的发光性能最好,在1587、1658 和1711 nm处有较强发射峰,分别对应Er3+的4I13/2→4I15/2跃迁和Tm3+的3F4→3H6跃迁。样品的上转换光谱表明,上转换荧光峰包括了蓝光、绿光和红光。

 Abstract: Er,Tm:Yb3Al5O12(Er,Tm:YbAG) nanopowder was synthesized by a gel method with citric acid as a combustion agent. The optimal preparation conditions for the sample obtained are Er3 + and Tm3 + doped mole concentrations of 2% and 1%, the mole ratio of citric acid to metal nitrate total number of atoms of 1.7:1, and calcination temperature and time of 950 ℃ and 2 h, respectively. The well-dispersed particles prepared appear spherical with the narrow size distribution, and the average particle size is 45 nm. The emission spectra of Er,Tm:YbAG nanopowder at room temperature were analyzed. The results show that the luminous properties of the 2%Er,1%Tm:YbAG samples is optimum, and the intensive emission peaks are located at 1587, 1658 nm and 1711 nm,which are corresponding to the 4I13/2→4I15/2 level transition of  Er3+ and the 3F4→3H6 level transition of Tm3+, respectively. It is indicated that the upconversion fluorescence peaks include blue, green and red lights.
