Abstract

Our main interest in this work is in the synthesis and improvement of the physical properties of TiO₂-based nanocomposites modified by coupling to Zn₂SiO₄:Mn (ZS:M) nanoparticles. The micro-structural characterizations carried out by using X-ray diffraction (XRD) and transmission electron microscopy (TEM) techniques of various TiO₂-ZS:M (Ti-ZS:M) samples at different temperatures revealed the formation of the anatase phase. The optical properties of TiO₂ modified by ZS:M nanoparticles shows a shift in absorption band toward UV region reflecting a significant an increase in the energy band gap for anatase phase at 3.36 eV, which is larger than the 3.06 eV found for the Dugussa P25 TiO₂. In this work, the influence of the annealing temperature on the microstructural, physico-chemical characteristics of the different samples is presented and their correlation with their photoluminescence in the visible spectral region has been investigated.
