以钛酸四丁酯为钛源，利用水热制备的纳米碳球为模板，通过超声辅助法合成了不同镝掺杂量的二氧化钛空心球。通过XRD、 SEM、 TEM、 EDX、 UV-Vis和荧光光谱对其形貌和光谱性质进行了表征，并讨论了镝掺杂前后对产物结构形貌的影响。研究结果表明，利用碳球为模板制备的镝掺杂的二氧化钛球尺寸可控且在430 nm附近发出宽而强的蓝光。
以鈦痠四丁酯為鈦源，利用水熱製備的納米碳毬為模闆，通過超聲輔助法閤成瞭不同鏑摻雜量的二氧化鈦空心毬。通過XRD、 SEM、 TEM、 EDX、 UV-Vis和熒光光譜對其形貌和光譜性質進行瞭錶徵，併討論瞭鏑摻雜前後對產物結構形貌的影響。研究結果錶明，利用碳毬為模闆製備的鏑摻雜的二氧化鈦毬呎吋可控且在430 nm附近髮齣寬而彊的藍光。

Dy( III ) -doped titanium dioxide hollow nanospheres were prepared by a chemical co -precipitation technique using carbon spheres as the template.The hollow nanospheres were characterized by X -ray diffraction(XRD), scanning electron microscopy ( SEM ) , transmission electron microscopy ( TEM ) , energy dispersive X -ray ( EDX ) analysis , and UV-vis spectra and fluorescent spectra.The influence of dysprosium doped on structure and morphology of the products was discussed.The results showed that the Dy ( III) -doped TiO2 hollow nanosphere of the ball size was controllable and emitted a wider and stronger blue light than that of undoped TiO 2 hollow spheres at about 430 nm.
