摘要
用液晶模板法,以非离子高聚物P123为模板,制备了掺Ce介孔稀土发光材料,并通过FT-IR和荧光光谱对其进行表征。着重通过对反应介质不同酸度(pH值)的研究来优化反应条件。结果显示:0.4为反应体系的最佳pH值,在这个pH值条件下,样品的荧光强度最强。
Mesoporous rare earth luminescence material with Ce was perapared by liquid-crystal template method using non-ionic P123 as the template, and the properties was characterized by FT-IR and fluorescence spectra. Reaction conditions were optimized by investigating the influence of different acidities of reaction systems. The results showed that when pH value of reaction solution was 0.4, the fluorescence intensity of sample materials reached the strongest level.
