4.Conclusion
In summary,nanocrystalline (1−x/2)TiO2•(x/2)Eu2O3 phosphors have been synthesized by surfactant-aided reverse micelles and solvothermal synthetic method.The crystalline phase obtained from both mixtures and nanocomposites was anatase type of TiO2 and the average particle size,measured by TEM,has been changed as a function of Eu concentration.The nanocomposites were supposed to be the nanostructure of TiO2 shell with locally concentrated Eu2O3 cores and the emissions from 5D0:Eu3+ were found in the sample having Eu2O3 aggregate in TiO2 matrix.The emission band centered at 614 nm due to the transition from 5D0 to 7F2 level was strong.Regardless of the change of excitation wavelength,Eu concentration,and temperature of the nanoparticles,the bandwidth and the wavelength of emission spectra were identical.It is suggested that the Eu3+ ions radiating the luminescence are under the same environment in the TiO2 nanoparticles.

4.结论
在摘要,nanocrystalline(1?x/2)TiO2?(x/2)Eu2O3 磷光质已经被表面活性剂综合-援助了反面的 micelles 和 solvothermal 合成物质方法.被从混合和奈米复合材料获得的水晶的状态是 TiO2 和被 TEM 测量的平均的粒子大小的 anatase 类型,已经被改变如一个 Eu 集中的功能.奈米复合材料应该用地方性集中的 Eu2O3 核心是 TiO2 贝壳的奈米结构和来自 5D0 的散发:Eu3 在样品中被发现在 TiO2 点阵式让 Eu2O3 聚集.由于转变,从 5D0 to 7F2 水平在 614个 nm 集中的散发乐团是强壮的.不管奈米粒子的刺激波长、 Eu 集中和温度的变化,带宽和散发频谱的波长是同一的.它被建议放射无热光的 Eu3 离子在 TiO2 奈米粒子的相同环境之下.

你的意思是什么？如果想翻译用金山快译吧。大概说的是纳米二氧化钛的合成。

结论
总之，纳米（ 1 -第X / 2 ）二氧化钛• （十/ 2 ），氧化铕荧光粉已合成了表面活性剂辅助反胶团和溶剂的合成方法。该晶相索取两种混合物和纳米复合材料的锐钛矿型二氧化钛及平均颗粒大小，其衡量的TEM ，已经改变为一个函数的欧盟浓度。纳米复合材料被认为将纳米二氧化钛壳牌与当地集中氧化铕内核和废物排放量的5D0 ：铕被发现在样品经氧化铕总量在二氧化钛矩阵。废气带为中心，在614 nm处，由于过渡的5D0 ，以7f2水平强。不论以何种变化激发波长，欧盟浓度和温度的纳米颗粒，带宽和波长的发射光谱完全相同。有人建议说，铕离子辐射发光是根据同一环境中，二氧化钛纳米粒子。
