Facile Synthesis and X-ray Peak Broadening Studies of Zn1-xMgxO Nanopaiticles
Magnesium-doped ZnO nanoparticles (NPs) (Zn1-xMgxO-NPs, x = 0.0, 0.01, 0.03, and 0.05) were synthesized by a simple sol-gel method. The compounds were synthesized at calcination temperatures of 650 degrees C for 2 h. The synthesized Zn1-xMgxO-NPs were characterized by X-ray diffraction analysis (XRD...
