Examining the Nanoparticles Thin Film of Nickel Oxide Produced Through Coriandrum Sativum Extract and Deposited by the Spin Coating Technique

Type: article
Abstract: As a great chelating agent, Coiandrum Sativum extract was used in the biosynthesis of NiO nanoparticles, which was an environmentally friendly process. The nanoparticles were then investigated by x-ray diffraction, FT-IR, and SEM. The result of SEM suggests that the nanoparticles have some agglomeration but are primarily spherical. After that, powdered nano-particles were used to make thin films, which were annealed for 60 minutes at (300 and 400) °C in the air. Atomic force microscopy (AFM) and X-ray diffraction (XRD) were utilized to determine the structural properties and composition of nickel oxide films, the films’ surfaces are smooth and that the crystalline geometry of the films is cubic. Following annealing at 400 °C, the nickel oxide layer’s surface profile is composed of uniformly sized ultrafine grains. The grain size increases from 39 to 46 nm with increasing the annealing temperature of the thin layer.
