Abstract
In the present work Pure and Cobalt (Co) doped Zinc Oxide (ZnO) Nanoparticles were synthesized by Sol-gel method. The effect of Co doping on structural and optical properties of Nanoparticles were investigated using X-Ray Diffraction (XRD), Scanning Electron Microscopy (SEM) and Fourier Transform Infrared (FTIR) spectroscopic characterization techniques. The XRD spectrum revealed the formation of Wurtzite structure of ZnO. The structural properties of nanoparticles including particle size and lattice strain were calculated from XRD data. SEM shows the morphology of Nanoparticles. The presence of functional groups was analyzed from FTIR spectra. The properties of Cobalt doped zinc oxide nanoparticles prepared through simple cost effective, Sol-gel method can be used in optoelectronics and thermally stable devices.
Highlights
In the recent years, researchers have been looking intensively at the use of nanomaterials due to their outstanding chemical and physical properties compared to bulk materials
In this work we report an investigation on structural and optical properties of Zinc Oxide (ZnO) particles doped with Cobalt ions [13]
X-Ray Diffraction (XRD) pattern of Pure ZnO nanoparticles consist of diffraction peaks for 2θ = 31.92 ̊, 34.54 ̊, 36.398 ̊, 47.59 ̊, 56.59 ̊ and 68.87 ̊ respectively
Summary
Researchers have been looking intensively at the use of nanomaterials due to their outstanding chemical and physical properties compared to bulk materials. Nanoparticles can contribute to stronger, lighter, cleaner and smarter surfaces and systems [1]. Today nano-structured materials have already been used in the manufacture of scratch proof eyeglasses, crack-resistant paints and anti-graffiti coatings for walls, transparent sunscreens, stain-repellent fabrics, self-cleaning windows and ceramic coatings for solar cells [2].
