摘要： 利用水热法制备了Y2O3和Y2O3:Eu3+，探讨了反应温度、反应时间及氢氧化钠溶液浓度对产物晶型的影响，确定了生成较好晶型的反应条件为：反应温度180℃，反应时间24 h，氢氧化钠溶液浓度2 mol/L. 研究了Y3+和Eu3+的配比对Y2O3:Eu3+荧光性能的影响. 结果表明，当n(Y3+):n(Eu3+)的比例为100:5时，其荧光强度最佳. TEM分析表明，Y2O3:Eu3+粉末具有直径约0.2~0.6 mm、长度为几到十几微米的棒状结构.

Abstract: Y2O3 and Y2O3:Eu3+ were synthesized by hydrothermal method, and the factors affecting product crystalline structure examined, such as reaction temperature, reaction time and NaOH solution concentration. The results showed that the reaction conditions for better crystal formation were with the temperature of 180℃, reaction time of 24 h and NaOH concentration of 2 mol/L. Additionally, the influence of the molar ratio of Y3+ to Eu3+ on their fluorescence properties was studied. When the ratio of n(Y3+) to n(Eu3+) was 100 to 5, the fluorescence intensity of Y2O3:Eu3+ exhibited best. TEM analysis showed that the morphology of Y2O3:Eu3+ particles demonstrated mainly microrods with the diameters of 0.2~0.6 μm and lengths of several micrometers.
