| Summary: | In this paper, we perform a theoretical study of the possible improvement of the absorption properties ( ) of the sample consisting of Fe3O4/C hollow sphere nanoparticles, prepared by sol-gel method. In order to achieve proposed goal, we examine the impact of the phase transformation of the sample, occurred during the annealing treatment. It was found that the presence of the Fhyd → Fe3O4 phase transformation, occurred during the thermal treatment process, decreases the absorption power of the final synthesis product. Accordingly, we considered ways to mitigate the effects of phase transformation as a mean of improving absorption efficiency. For this purpose, we propose a theoretical framework that relies on a simple quantum mechanical Hamiltonian. We suggest that the absence of the Fhyd → Fe3O4phase transformation, could improve the absorption properties of the final sample (Fe3O4/C). |
