Abstract

Pure and doped TiO2 with Eu3+ nanoparticles were prepared by a novel and simple preparation method. The pure TiO2 nanoparticles and the doping TiO2 with the Eu3+ ions prepared at room temperature by the sol-gel method via the reaction of Titanium (IV) isopropoxide (TTIP) with an aqueous solution of hydrochloric acidic in the presence of ethanol. The crystal structure of the prepared nanoparticles was investigated by X-Ray Diffraction (XRD) while the morphology of the samples was investigated by Field Emission Scanning Electron Microscopy (FESEM). All the prepared samples having excellent crystalline. As well, XRD proved that doping TiO2 with Eu3+ reduced the crystallite size. The FESEM images showed that the doping of TiO2 with Eu3+ results in larger particle sizes. In the present work, the effects of doping, particle size, and stabilization of the anatase phase were studied. As well as the deceleration of crystal growth by the rare-earth-doped into TiO2 host was investigated.
Eu3+:TiO2纳米颗粒的合成及结构性能
采用一种新颖、简单的制备方法制备了Eu3+纳米颗粒的纯TiO2和掺杂TiO2。以异丙酸钛(TTIP)与乙醇存在的盐酸水溶液为原料,采用溶胶-凝胶法制备了纯TiO2纳米粒子和掺杂Eu3+离子的TiO2。采用x射线衍射(XRD)和场发射扫描电镜(FESEM)研究了制备的纳米颗粒的晶体结构。所制备的样品均具有优异的结晶性。XRD也证明了Eu3+掺杂TiO2可以减小晶粒尺寸。FESEM结果表明,Eu3+掺杂后TiO2颗粒尺寸增大。在本工作中,研究了掺杂、粒度和锐钛矿相稳定性的影响。同时研究了稀土掺杂TiO2载体对晶体生长的抑制作用。
