以稀土氧化钕和邻非罗林为原料，合成了两种新型钕离子络合物液体激光介质，实验测得该液体激光介质无毒、成本低、热稳定性好，并且易于工业化.在考虑交叉驰豫的情况下，测量了样品的吸收谱和荧光谱，得到Nd3+“绿色”液体激光介质激发过程中各能级粒子数的速率方程，并利用速率方程研究了4F3/2能级荧光强度和Nd3+浓度的关系.结果表明：随着浓度的增加，荧光强度出现先增后减的现象；分析了液体运行温度对样品荧光强度的影响，得到了荧光强度对温度的依赖关系——由于双声子辅助能量转移过程，随着温度的增加，液体荧光强度迅速下降.

Double novel neodymium complex liquid laser medium were prepared based on Neodymium Oxide and 1, 10Phenanthroline. This laser medium was nontoxic, low cost, and well thermo stability. When cross relaxation was considered, the rate equations of every level particle were obtained while Nd3+ “green” novel liquid laser medium was excited. The relation between Nd3+ concentration and 4F3/2 luminescence strength was researched using rate equations, while absorption spectrum and luminescence spectrum were measured. The results show that the luminescence strength increases with concentration firstly and then decreases with concentration. The relation between operation time and luminescence strength are also researched.
