Aerosol route in processing of nanostructured phosphor materials#

Among the methods currently used for nanophase processing, synthesis through dispersion phase (aerosol) enables generation of ultrafine powders with controlled stoichiometry. It represents a “bottom-up ” chemical approach that provides control over a variety of important parameters enabling the formation of either amor-phous, nanocrystalline or metastable phases. Particularly, the opportunities of the hot wall aerosol synthesis, i.e. spray pyrolysis, for the generation of ultrafine phosphor particles with uniformly distributed components, nano-clustered inner structure and luminescence properties is demonstrated in following systems: Gd2O3:Eu
