| Summary: | 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 amorphous, 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, Y2O3:Eu, (Y1-xGdx):Eu and Y3Al5O12:Ce, highlighting the research activities in the Institute of Technical Sciences of SASA, Serbia and the University Carlos III, Madrid, Spain in the framework of COST 539 Action.
