Abstract: | Titanium oxide nanocrystals synthesized by the Pechini method were calcinated at temperatures between 300 and 1000 C. The crystalline structure was analysed by X-ray diffraction, scanning electron microscopy (SEM) and Raman spectroscopy. A phase transition from the anatase to rutile crystalline phase was found to occur at temperatures near 500 C. The samples were characterized by photoluminescence (PL) and dielectric spectroscopy. The influence of the calcination temperature on the visible and near infrared luminescence is discussed. A correlation between the structural properties, luminescence and dielectric properties are discussed. |
