Abstract

Mg-doped ZnO (Mg_xZn_1−xO, x = 0–0.10) nanoparticles were prepared by sol–gel method. Structural characterization by X-ray diffraction (XRD) indicates that the lattice parameter a increases and c decreases linearly with the increase in Mg content (x) due to the substitution of Mg²⁺ for Zn²⁺ in ZnO lattice. The blueshift of Raman modes is observed, impling the increase in force constant of atom vibration in the Mg_xZn_1−xO (MgZnO) nanoparticles. Resonant Raman spectra show longitudinal optical phonon overtones up to fifth order, revealing that the short part of the electron–phonon interaction is enhanced and long-range part is weakened by Mg doping.
