Abstract :
Pure and doped TiO2 with Eu3+ nanoparticles were prepared by a novel
and simple preparation method due to their wide spectrum of applications
such as solar cells, gas sensors photocatalyst, etcetera. 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.
