Investigation of the structural, optical, elastic and electrical properties of spinel LiZn₂Fe₃O₈ nanoparticles annealed at two distinct temperatures.

ABSTRACT: Nanoparticles of Li_0.5ZnFe_1.5O₄ (LiZn₂Fe₃O₈) with the spinel structure were prepared by a sol-gel auto-combustion method at two different annealing temperatures. X-ray diffractograms and Rietveld refinement confirmed the formation of the spinel structure. The morphology was analyzed by electron microscopy, which showed that the grains were composed of different crystallites. Elastic properties were determined from infrared spectroscopy. It was found that the elastic parameters increased with the increase in annealing temperatures. The band gap depends on the annealing temperature and it decreased on increasing the particle size. The conductivity of the specimen annealed at 500 °C followed either the Jonscher's model or Drude
