Preparation and study of the structural and optical traits of Ag: Zro2 nanostructure thin films prepared via spin coating: Effect of spin speed on thin films properties

Abstract

Thin films of silver: zirconium oxide (Ag: ZrO2), prepared using the spin coating method (SCM) with 2% silver nitrate (Ag NO3) and 1% zirconium nitrate (Zr (NO3) 4) on glass substrate at room temperature, with different spin speeds (1000, 2000 and 3000) rpm. X-ray diffraction (XRD) and Field Emission scanning electron microscopy were used to investigate the structural properties of the grown silver films. The optical properties of these thin films were distinguished by UV-vis spectroscopy. The films' polycrystalline nanostructure was revealed by X-rays, and the grain size shrank with increasing spin speed (from 1000 to 3000 rpm). The scanning electron microscope showed that the average particle size also decreases from (80.7 - 42.67) nm with an increase in the spin speed from (1000 - 3000). and Uv-vis spectroscopy showed that the transparency of the films increases, while the absorbance, coefficient attenuation, and absorption coefficient of the films decrease when the spin speed increases
