This thesis is devoted to a study of flame aerosol deposition (FAD) of advanced phosphor coatings. FAD combines synthesis of phosphor particles by flame spray pyrolysis with their deposition onto a substrate in a single processing step. Y2O3:Eu phosphor was chosen as the main test material. The mean particle size of the phosphor powder produced by droplet-to-particle conversion (DPC) of aqueous solutions of rare earth nitrates could be varied in the range 180 ¿ 500 nm. It was found that the screens deposited from concentrated precursor solutions ( ~ 0.5 µm) achieved the brightness of the sta...
