Synthesis of Se doped CdO nanoparticles by sol-gel method, determination of structural and morphological properties

Abstract

In this study, pure and Selenium (Se) doped Cadmium oxide (CdO) nanoparticles were synthesized by Sol-gel production method. Cadmium acetate dihydrate (C₄H₆CdO4 · 2H₂O) was used as a cadmium source, and (Na₂SeO₃) was used as a selenium source. The structural and morphological properties of the synthesized nanoparticles were determined by Field Emission Scanning Electron Microscopy (FE-SEM), X-Ray Diffraction (XRD), Energy-dispersive X-ray spectroscopy (EDX) and Fourier Transform Infrared Spectroscopy (FT-IR) analyzes. As a result of the analysis, it was seen that Se doped CdO nanoparticles were produced successfully by sol-gel method. The produced nanoparticles are composed of almost spherical nanostructures. Particle sizes changed with Se doping and the smallest particle size was reached in the sample with 5% Se additive. The Se doping caused changes in unit cell volumes and crystal sizes of nanoparticles. The results show that the produced nanoparticles can be used in electronic devices containing semiconductor metal oxide.
