Thirumalai, R. Chandramohan, T. Vijayan] Monodispersed Gd2O2S:Eu3+ nanostructures with tunable morphologies have been selectively fabricated by solvothermal method in the presence of stable inorganic precursors avoiding metalorganic precursors. The size and morphology of the products were controlled successfully by adjusting the reaction conditions. The products were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), selected-area electron diffraction (SAED) and X-ray photoelectron spectroscopy (XPS). The corresponding UV absorption and photoluminescence excitation spectra show a significant blue-shift confirming the quantum confinement effect. A possible growth mechanism for the formation of monodispersed Gd2O2S:Eu3+ nanocrystals has been proposed. The luminescence mechanism and the size dependence of their fluorescence properties are also discussed. Springer Science+Business Media, LLC, 2010 Thirumalai J.
