本文引入与浓度和厚度有关的kNL待定参数, 在J-O理论基础上, 对Er3+/Yb3+掺杂的LiNbO3和LiTaO3单晶衬底上 的多晶水热外延样品进行了基于吸收光谱的拟合计算. LiNbO3:2=2.34 10-20 cm2,4=0.77 10-20 cm2,6=0.3110-20 cm2, kNL=4.32 10-2 molm-2. LiTaO3:2=1.6810-20 cm2,4=0.8410-20 cm2,6=0.4510-20 cm2, kNL=9.1710-3 mol m-2. 该方法可尝试推广到粉体或胶体等难以直接获得浓度和厚度数据的体系. 经上转换发光测试及光谱参数计分析认为Er3+/Yb3+离子的掺杂浓度比为1:1的情况下, 样品呈现绿色上转换发光光谱; 可尝试以降低基质声子能量的方法提高4I13/2能级 对2H11/2和4S3/2能级的量子剪裁效率.In this paper we introduce the undetermined parameter kNL which is related to the concentration and thickness, and perform the fitting calculation that is on the basis of the absorption spectrum about the hydrothermal epitaxial polycrystalline sample on the surfaces of LiNbO3 and LiTaO3 doped with Er3+/Yb3+ single crystalline substrates according to the J-O theory at the room temperature. It is obtained that for LiNbO32=2.34 10-20 cm2,4=0.77 10-20 cm2,6=0.31 10-20 cm2, and kNL=4.32 10-2 molm-2. LiTaO32=1.68 10-20 cm2,4=0.84 10-20 cm2,6=0.45 10-20 cm2, kNL=9.17 10-3 mol m-2. This method can be extended to the systems in which the data of concentration and thickness such as powder or colloid are difficult to obtain. According to the up-conversion luminescence analysis and the calculation via spectrum parameters, it is confirmed that both the samples have the green up-conversion luminescence at Er3+:Yb3+=1:1, the method of reducing the energy of matrix phonon is tried to improve the quantum cutting yield of 4I13/2 to 2H11/2 and 4S3/2.
