Optical Properties of Pure and Gd3+ Doped Titanium Dioxide

Pure and Gd3+ doped Titanium dioxide nanocrystals were prepared using the sol – gel method. Titanium isopropoxide (TIP) was used as the precursor for Titania sol preparation. X-ray powder diffraction confirms that the particles crystallize purely in anatase phase and the broadening of Bragg’s peaks ascertains smaller particles size. The formation of uneven spherical grains composed of small primary titania particles are observed from SEM. The UV-Vis spectral analysis was carried out between 200 nm and 800 nm. More over the presence of Gadolinium had resulted in a shift of 10 nm from the undoped TiO2. The FT-IR and FT-Raman spectra confirmed the anatase phase of Titanium dioxide.
