Abstract
This study reports the synthesis of high dielectric constant zirconia oxide (ZrO2) nanorods (NRs) via a co-precipitation method followed by calcination at 700 °C for 2 h. X-ray diffraction (XRD) confirms a mixed-phase composition of orthorhombic and monoclinic structures, while transmission electron microscopy (TEM) reveals distinct nanorods. Energy dispersive X-ray analysis (EDAX) verifies the elemental composition. Photoluminescence (PL) spectroscopy indicates band gap energy of 1.9 eV, aligning better with orthorhombic zirconia. UV–vis analysis suggests oxygen vacancy defects potentially influencing the optical properties due to the nanorod morphology. Importantly, dielectric studies show a high dielectric constant of 29 at 1 MHz, which is approximately four times higher than commercially available ZrO2.
