| Abstract: | Using AgNO3 and NH4 VO3 as raw materials, Eu2 O3 acted as metal source , P123 as the structure -director agent, ethyl alcohol and water as mixture solvent, urchin-like Eu2O3/Ag3VO4 microspheres were obtained by hydrothermal method , and the conditions of synthesis were also studied . The samples were characterized by SEM , XRD and XPS , moreover , the formation mechanism of urchin-like Eu2 O3/Ag3 VO4 was discussed , too.The results show that the diameter size of prepared urchin-like Eu2 O3/Ag3 VO4 microspheres is about 4-5 μm when the reaction temperature is 80 ℃ and the reaction time is 10 h.The effect of photoluminescence properties of Eu 3+ doping content in the samples was investigated , and when the Eu 3+doping content was 4%, the samples have the best photoluminescence properties . |
