| 摘 要： | 在温度为80℃、pH值为1~2的酸性条件下制备出了聚丙烯酰胺改性的SrAl2O4:Eu2+,Dy3+发光材料。采用红外吸收光谱、热失重和荧光光谱等对改性的发光材料进行了表征和性能测试,并通过pH值测定结果和沉降实验对改性的发光材料的耐水性和分散性进行了测定。结果表明,改性后的发光材料中包含了聚丙烯酰胺改性剂,发光强度降低了约2%,但对其发光性能无太大影响,经聚丙烯酰胺改性后,发光材料的耐水性和分散性得到明显地改善。

| Abstract: | Luminescent materials,which based on alkaline earth aluminate(SrAl2O4:Eu2+,Dy3+),was modified by polyacrylamide in condition of 80 ℃,pH=1～2.The resulting luminescent materials were characterized and analyzed by IR,TG and light-decay spectrum.Their properties of water resisting and dispersion were also investigated by using pH and sedimentation test.It was found that the modification for luminescent materials covered by polyacrylamide,and the luminescent intensity decreased 2%,but it had no effect on their photoluminescence performances,their properties of water resisting and dispersion were obviously improved. |
