ZnAl(2)O(4):Eu(3+) hollow nanophosphors have been for the first time prepared by using carbon nanospheres as hard templates. The ZnAl(2)O(4):Eu(3+) hollow nanophosphors were well characterized by means of XRPD, FESEM, TEM, HRTEM, N(2) adsorption and desorption and PL techniques. The N(2) adsorption and desorption data reveal the porous nature of ZnAl(2)O(4):Eu(3+) hollow nanophosphors and high surface area of 195.3 m(2) g(-1). The PL measurement illustrates red-emitting feature of ZnAl(2)O(4):Eu(3+) hollow nanophosphors arising from the characteristic transitions of Eu(3+) from (5)D(0)→(7)F(j) (j=0, 1, 2, 3, and 4). This simple and efficient synthetic strategy could be extended to prepare other series of aluminates nanophosphors with novel hollow structures.
ZnAl(2)O(4):Eu(3+) 空心纳米荧光粉首次采用碳纳米球作为硬模板进行制备。采用 X 射线粉末衍射（XRPD）、场发射扫描电子显微镜（FESEM）、透射电子显微镜（TEM）、高分辨率透射电子显微镜（HRTEM）、氮气吸附-脱附和光致发光（PL）技术对 ZnAl(2)O(4):Eu(3+) 空心纳米荧光粉进行了全面的表征。氮气吸附-脱附数据表明 ZnAl(2)O(4):Eu(3+) 空心纳米荧光粉具有多孔性，比表面积高达 195.3 m(2) g(-1)。PL 测量表明，ZnAl(2)O(4):Eu(3+) 空心纳米荧光粉具有红色发光特性，这源于 Eu(3+)从 (5)D(0)→(7)F(j)（j=0、1、2、3 和 4）的特征跃迁。这种简单高效的合成策略可以扩展到制备具有新颖空心结构的其他系列的铝酸盐纳米荧光粉。
