Abstract

In the present work, the hydrothermal method was used to synthesize mixed phase zirconium oxide (ZrO2) nanopowder. X-ray diffraction and scanning electron microscopy were employed for structural and morphological study, respectively. Fourier transform infrared spectroscopy confirms the presence of the Zirconium-Oxygen bond. To study the optical properties of ZrO2 nanopowder, Raman and Ultra-Violet visible spectroscopies were used at room temperature. The Tauc’s plot reveals that the average value of the optical bandgap is ∼ 3.4 eV. These studies of dual-phase ZrO2 nanopowder suggest that ZrO2 nanopowder can be a suitable candidate for many potential applications including optoelectronic devices and optical sensors.
