摘　　要：采用水热法制备了纳米带状结构的Zn3V2O8多晶粉体,并对Zn3V2O8漫反射光谱以及发射谱、激发谱进行了分析。结果表明,在230-450 nm波长范围为全吸收,激发谱上有一个宽带激发与窄带激发,峰值分别位于350 nm与272 nm。在发射谱上的宽带发射与窄带发射,峰值分别在528 nm与716 nm。降解率实验结果表明了当光照时间延长到3 h后,水热合成Zn3V2O8基本已完全降解亚甲基蓝溶液。The poly crystalline Zn3V2O8 powders with ribbon shape nanostructure were prepared by hydrothermal method. The samples were investigated by emission spectrum, excitation spectrum and diffuse reflectance spectra. The results show that the absorption region is located in 230450 nm. The excitation spectrum has respectively a broad band with peak value of 350 nm and a narrow band with peak value of 272 nm. The emission spectrum has also a broad band with peak value of 528 nm and narrow band with peak value of 716 nm. The analyzing results of the degradation show that the synthesized Zn3V208 can completely degrade the methylene blue solution after light illuminate 3 h.
