采用不同表面活性剂，采用熔盐法制备了一系列Y2O3:Eu3+红色荧光粉。在室温下研究了它们的结构、形态和光致发光特性。 Y2O3:Eu3+的粒径可以通过调节表面活性剂的种类来控制。采用NP-10[聚氧乙烯(10)壬基苯基醚]制备的荧光粉Y2O3:Eu3+具有规则的形貌和较高的结晶度，其平均粒径约为200 nm。在254 nm激发下，肉眼可以观察到红色荧光粉发出明亮的红光。
A series of red phosphors Y2O3:Eu3+ were prepared by the molten salt method with different surfactants. Their structures, morphologies, and the photoluminescent properties were investigated at room temperature. The particles size of Y2O3:Eu3+ can be controlled by adjusting the kinds of surfactants. The phosphor Y2O3:Eu3+ prepared with NP-10 [polyoxyethylene (10) nonyl phenyl ether] shows regular morphology and higher crystallinity, and its average particle size is about 200 nm. Bright red light can be observed by naked eyes from the red phosphor under 254 nm excitation.
