中文摘要：
采用溶胶-凝胶法制备丁TiO2和Eu3＋离子掺杂的TiO2纳米材料，通过x射线衍射和荧光光谱分析对样品进行，表征。X射线衍射结果表明，少量稀土Eu3＋离子的掺杂能有效抑制TiO2纳米颗粒的增长，进而提高晶体相变温度；荧光光谱研究表明TiO2：Eu3＋体系中均能得到Eu3＋离子特征发射光谱。随着Eu3＋离子含量的增加，Eu3＋离子的发光性能增强；并且Eu3＋离子以Eu3＋（樟脑酸）。（1，10-菲咯啉）：有机配合物为前驱体掺杂到TiO2：Eu3＋纳米晶体的发光性能优于以Eu（NO3）3·6H2O为前驱体制备的TiO2：Eu3＋纳米晶体。
英文摘要：
Titania and Eu3- doped titania nanocrystals were prepared by sol-gel method. The samples were characterized by XRD and photoluminescence （PL） spectra. The XRD results showed that parti- cle size of titania remarkably became smaller and the phase changed temperature of crystals was in- creased with the Eu3- doping. As a result, the phase changed temperature o{ crystals was increased. And the PL spectra resulted revealed that the properties of Eu3＋ doped in titania system were obviously improved. With the content of Eu3＋ increasing, PL property was greatly improved. Furthermore, the PL property of nanocrystals synthesized by Eu2 （camphoracid） 3 （1,10-phenanthroline） 2 precursor was much better than that prepared by Eu（NO3）3 · 6H2O precursor.
