The aim of the work is to study a new method of thermochemical synthesis of luminescent powder of lutetium-aluminium garnet activated by cerium ions (Lu3Al5O12:Се3+) using nitric acid salts of lutetium, aluminium and cerium, and a mixture of acetic acid and polyvinyl alcohol as a propellant. The synthesis process was carried out in a muffle furnace at an initial temperature of 350 ºC under conditions of limited presence of atmospheric air. The average size of the coherent scattering region for Lu3Al5O12:Се3+ obtained from the combustion reaction is 60 nm. It was found that during the preparation of nanostructured powder in the reaction vessel the temperature sufficient for the synthesis of Lu3Al5O12 develops, and the reducing environment arising from the combustion of the organic mixture favours the formation of cerium ions in the tricharged state. The emission spectrum of the obtained LuAG:Ce3+ luminophore powders shows a broad band due to the energy transitions of the Ce3+ ion in the garnet structure, between 500 and 650 nm under excitation with a wavelength of 450 nm, which corresponds to the green emission colour.
