Abstract

Synthesis and fabrication are the two essential steps to design any electrical or electronic device. In composites preparation, It is necessary to maintain uniform particle distribution, shape, size, atomic bonding, and good adhesiveness to substrates. In this work, 1 wt. % SnO2 doped ZnO-TiO2 ternary metal oxide composite was prepared by the conventional solid-state method. Hydroxypropyl Cellulose (HC), Sodium dodecylbenzene sulfonate (SDS) surfactants were used, and their effects on composite were investigated. The composites’ structural, optical, and morphological properties were distinguished by X-ray diffraction (XRD), UV-Visible spectroscopy (UV-Vis), and the Field emission scanning electron microscope (FESEM). Debye Scherrer, Williamson-Hall methods were performed to determine Crystallite size. Optical bandgaps were calculated by Tauc’s plot method. The results revealed that ZnO-TiO2-SnO2 composite modified with Hydroxypropyl Cellulose (HPC) generates optical bandgaps at 2.6 eV, and crystallite size is 14-20 nm. Homogeneous distribution of particles is observed.
