The synthesis is carried out by using the co-precipitation method using optimum content of zirconium oxychloride octahydrate (ZrOCl<sub>2</sub>.8H<sub>2</sub>O) with NaOH solution at a calcination temperature of 700°C. The synthesized samples were characterized to ensure structural, functional, morphological, and chemical composition by several techniques. The monoclinic structure has been confirmed from XRD, SAED, and Raman spectra. The Zr-O stretching vibration and Zr-O<sub>2</sub>-Zr bending vibrations were confirmed through FTIR analysis. The well-dispersed particles with spherical morphology were established through SEM and TEM analyses. EDX spectra confirmed the formation of pure zirconium oxide. The bandgap was calculated with the help of UV-Vis spectra and particle size was determined from XRD data using Debye Scherrer’s equation. The variation of bandgap and particle size compared with different concentrations of precursor solution was studied.</p><p>BIBECHANA 18 (1) (2021) 1-9</p> ER -
