The ZnO, TiO2, and ZnO-10 wt% of TiO2 and TiO2-10 wt% ZnO nanoparticles are synthesized by solution combustion synthesis at 200 C. The crystal structure of the four samples are analyzed by X-ray diffractometer (XRD). XRD results suggest that the crystal properties of the doped samples improved without any effect on the parent lattice. The morphological and optical properties of the TiO2-doped ZnO sample are characterized by scanning electron microscopy and UV-Vis spectroscopy. The IR and Raman laser observations indicate that the compounds consist of Ti- O and Zn-O bonds, suggesting that the prepared compounds are indeed pure. An upward shift, which is most likely due to the doping material, is observed in the absorption studies. This article discusses the structural, optical, and morphological properties that are changed with the doping concentrations. © 2018 American Scientific Publishers
