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 T iO2-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 T iO2. 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.

One of the current research focus of global scientific community is on the development of advanced nano materials for applications in the field of catalysis, medicine, semiconducting industry and optoelectronic devices [1–3]. Nanomaterials have stimulated enthusiasm in various fields of research, due to several factors such as the emergence of new analytical techniques allowing access to direct observation of nano-sized objects in addition to the many potential applications in various fields (lighter and/or more resistant materials, greater magnetic recording capacities, catalysts, nanostructured traps to trap pollutants from indust
