摘要

Air stable organoindium complex, [MeIn{SeC4H(Me-4,6)(2)N-2)(2)] (1) have been synthesized by the treatment of MeInCl2 with NaSepymMe(2). The complex was characterized by elemental analyses, NMR spectroscopy and scXRD technique. Thermolysis of 1 in OAm/ODE and OAm/OA resulted in beta-In2Se3 nanosheets and gamma-In2Se3 nanobullets, while the same complex thermolyzed together with Cu(acac)(2) yielded CuInSe2 nanostructures. The complex has also been used for the deposition of indium selenide thin films by aerosol-assisted chemical vapor deposition on different substrates at 400 and 450 degrees C. Crystal structure, elemental composition, and bandgap of these materials were investigated by p-XRD, EDS, and DRS technique, respectively. The morphology, surface topography, and roughness of these materials were determined by HRTEM, SEM, and AFM. SEM micrographs of the thin films revealed porous sheets. The direct bandgap of these materials was blue-shifted relative to the bulk material.
