Abstract
The preparation of bis(N-cyclohexyl-salicydenaminato)manganese(II) complex as a precursor for the fabrication of Mn3O4 nanocrystalline thin films is reported. The manganese oxide thin films were chemically deposited on glass and silicon substrates by spin-coating and effect of the annealing temperature on the thin films has been systemically investigated. The optical absorption and emission spectra of all the Mn3O4 thin films were red-shifted when the temperature was raised. The optical band gap energies were determined and found to be decreasing as the annealing temperature was increasing. X-ray diffraction patterns confirmed the formation of tetragonal phase structures with lattice parameters of a = b = 5.75 Å and c = 9.44 Å. SEM micrograms disclosed an improvement in crystallinity of the particles on the surface of the substrate when the temperature was increased.
