Abstract
MgxZn1-xO (0 ≤ x ≤ 0.4) nanoparticles were synthesized by direct thermal decomposition of Zn and Mg acetates in air at 500
ºC. As revealed by SEM, pure ZnO sample consisted of nanorods, wheras MgxZn1-xO samples became nanoparticles. The
Eg increased from 3.13 to 3.22 eV with increasing Mg concentration. The PL spectra of all the samples showed a strong UV
emission, a weak blue, a weak blue-green, and a weak green bands, indicating their high structure and optical quality.
