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.
