Abstract

Structural, Optical and Antibacterial Response of CaO Nanoparticles Synthesized via Direct Precipitation Technique

Highlights

The materials research in the past few decades dedicated to the metal oxide semiconductors (MOS) because of their enormous applications in many fields including photocatalysts, sensors, photonics, agriculture, electronics, optoelectronics, magnetism, superconductivity, environmental remediation, energy storage and conversation, biomedical materials, etc. [1,2,3,4,5,6,7,8]
This specifies that the surface –OH and the lattice oxygen of Calcium oxide (CaO) nanoparticles make available oxygen which is more liable on the high surface area of the nanoparticles [16]
The synthesized nanoparticles are characterized for different features using Fourier transform infrared (FTIR), X-ray diffraction (XRD), FE-SEM, energy dispersive X-ray spectroscopy (EDS) and diffuse reflectance spectroscopy

Summary

Introduction

The materials research in the past few decades dedicated to the metal oxide semiconductors (MOS) because of their enormous applications in many fields including photocatalysts, sensors, photonics, agriculture, electronics, optoelectronics, magnetism, superconductivity, environmental remediation, energy storage and conversation, biomedical materials, etc. [1,2,3,4,5,6,7,8]. The synthesized nanoparticles are characterized for the structure, morphology, chemical composition and optical behavior using Fourier transform infrared (FTIR) spectroscopy, X-ray diffraction (XRD), field effect scanning electron microscopy (FESEM), energy dispersive X-ray spectroscopy (EDS), and diffuse reflectance spectroscopy. The XRD results show that the CaO nanoparticles have been synthesized in a cubic crystalline structure with the average crystallite size of about 13 nm and display aggregated morphology of nanoclusters.
