摘　　要：为了得到性能优异的纳米发光材料,实验以稀土硝酸盐-葡萄糖的混合液做为前驱体,采用一步水热法和随后的热处理,得到了Y_(2)O_(3)∶Eu^(3+)纳米结构空心球,并用场发射扫描电子显微镜、X射线衍射、透射电子显微镜、X射线能量色散光谱和荧光光谱等测试手段对所得样品进行了表征。结果表明:所得样品为微米尺寸的Y_(2)O_(3)∶Eu^(3+),具有规则的空心结构;Y_(2)O_(3)∶Eu^(3+)空心球的壁层由尺寸为30 nm左右的Y_(2)O_(3)∶Eu^(3+)纳米晶构成,部分纳米晶之间存在一定程度的结构有序性。另外,发光性质测试结果表明:所合成的纳米结构空心球具有较好的发光性能。In order to obtain nano luminescent materials with excellent performance,Y_(2)O_(3)∶Eu^(3+)nanostructured hollow spheres were prepared by one-step hydrothermal method and subsequent heat treatment with the mixture of rare earth nitrate and glucose as the precursor,and the samples were characterized by field emission scanning electron microscopy,X-ray diffraction,transmission electron microscopy,X-ray energy dispersion spectroscopy and fluorescence spectroscopy.The results show that the sample is Y_(2)O_(3)∶Eu^(3+)with micrometer size and regular hollow structure;The wall layer of Y_(2)O_(3)∶Eu^(3+)hollow sphere is composed of Y_(2)O_(3)∶Eu^(3+)nanocrystals with a size of about 30 nm,and some nanocrystals are structurally ordered.In addition,the photoluminescence property test results show that the synthesized nanostructured hollow spheres have good photoluminescence properties.
