分别采用碱催化法、酸催化法及种子法合成 Eu3+掺杂 SiO 2微球。结果表明：种子法为合成 Eu3+掺杂 SiO 2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。
分彆採用堿催化法、痠催化法及種子法閤成 Eu3+摻雜 SiO 2微毬。結果錶明：種子法為閤成 Eu3+摻雜 SiO 2微毬的最佳閤成方法，所得產物為粒徑均一(直徑370~380 nm)、單分散性和毬形度均較好的微毬；在紫外光激髮下，微毬錶現齣較彊的 Eu3+特徵紅光髮射。

Three methods (base-catalyzed method,acid-catalyzed method and seed growth method) have been used to prepare SiO 2 ∶Eu3 + microspheres.Meanwhile,optimal synthesis conditions of the SiO 2 ∶ 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,monodispersity and sphericity.The final SiO 2 ∶Eu3 + microspheres showed a strong red emission under ultraviolet excitation.
