Abstract
⺠Effects of Co content and temperature on the cation distribution in CoxMg1âxAl2O4 nanoparticles are studied. ⺠Mg2+ and Co2+ ions occupy both tetrahedral and octahedral sites in the nanoparticles. ⺠The secondly octahedral Al3+ ions are observed besides the above two coordination sites. ⺠Inversion parameter of the samples decreases with the increase of annealing temperature and cobalt content. ⺠Optical properties of the nanoparticles are discussed on the basis of the structural results.
