Luminescent properties of rare earth samarium complex/alkyd resin composites

制备了Gd_(0.5)Sm_(0.5)(BA)_3Phen·H_2O的醇酸树脂掺杂复合材料。通过元素分析、红外光谱、紫外光谱及荧光光谱测试,确定了配合物的组成及结构,并研究了其荧光性质。实验结果表明,复合材料中稀土配合物的掺入量为0.6%时,制得的醇酸树脂荧光材料以365nm激发能发出稳定、具有良好发光强度的橙红色荧光;复合材料的制备最佳工艺条件为:温度为55℃,搅拌速率为600r/min,反应时间为5h。

The alkyd resin doped composites of Gd0.5 Sm0.5（BA）3 Phen·H2 O were prepared.The compositions and structures of the complexes were determined by elemental analysis,infrared spectroscopy,UV spectroscopy and fluorescence spectroscopy.The experimental results show that the composites excited at 365 nm have stable orange red luminescence when amount of the doped rare earth complex in alkyd resin is 0.6%.The optimal conditions for preparation of the composite are as follows,stirring rate 600 r/min,temperature 55 ℃,reaction time 5 h.
