摘要:

分别采用碱催化法、 酸催化法及种子法合成Eu3+掺杂SiO2微球. 结果表明: 种子法为合成Eu3+掺杂SiO2微球的最佳合成方法,  所得产物为粒径均一(直径370~380 nm)、 单分散性和球形度均较好的微球; 在紫外光激发下, 微球表现出较强的Eu3+特征红光发射.

关键词: Eu3+掺杂, 单分散性, SiO2微球, 种子法

Abstract:

Three methods (basecatalyzed method, acidcatalyzed method and seed growth method) have been used to prepare SiO2∶Eu3+ microspheres. Meanwhile, optimal synthesis conditions of the SiO2∶Eu3+ microspheres were obtained. The results indicate that the best method was the seed growth method, by which the average diameters of obtained particles are approximately 370—380 nm, and the final product has nice homogeneity, monod
ispersity and sphericity. The final SiO2∶Eu3+ microspheres showed a strong red emission under ultraviolet excitation.
