以硝酸银和氧化铕为金属源,P123为结构导向剂,乙醇和水为溶剂。本文通过前驱体合成路线,采用水热法得到海胆状Eu_2O_3/Ag_3VO_4微球,并探讨其合成条件;采用SEM、XRD、XPS等方法对样品进行了表征,并探讨了Eu_2O_3/Ag_3VO_4海胆状微纳米结构的形成过程。测试结果表明:在反应温度为80℃,反应时间为10 h时,所合成的海胆状Eu_2O_3/Ag_3VO_4微球直径约为4~5μm。针对合成的样品,研究了海胆状Eu_2O_3/Ag_3VO_4微球的光致发光性能,并考察Eu~(3+)掺杂量对光致发光性能的影响,当Eu~(3+)掺杂量为4%时,样品具有最好的光致发光性能。
Silver nitrate and europium oxide as the metal source, P123 for the structure-oriented agent, ethanol and water as the solvent. In this paper, sea urchin-like Eu_2O_3 / Ag_3VO_4 microspheres were obtained by hydrothermal method and the synthesis conditions were discussed. The samples were characterized by SEM, XRD and XPS, and the Eu_2O_3 / Ag_3VO_4 sea urchin-like micro / nano The formation of the structure. The results showed that the diameter of Eu_2O_3 / Ag_3VO_4 beads was about 4 ~ 5μm when the reaction temperature was 80 ℃ and the reaction time was 10 h. For the synthesized samples, the photoluminescence properties of sea urchin-like Eu_2O_3 / Ag_3VO_4 microspheres were studied, and the effect of Eu 3+ doping on the photoluminescence properties was investigated. When the Eu 3+ doping amount is 4%, the sample has the best photoluminescence properties.
