New combustion technology of synthesis of nanosize phosphors have been described. Four series of nanocrystalline Lu2O3:Eu3+ have been prepared for different composition of fuel (glutamic acid:glycine)(!) using the combustion method. The concentration of Eu(III) varied from 0.05 to 15wt% and the size of the nanoparticles covered the range 6-10nm. The size effect on optical properties of the phosphors have been investigated and correlated with the decay profiles of the Eu(III) emission. It has been proved that composition of the fuel influences the size of nanocrystallines, and in consequence their optical properties

Abstract
New combustion technology of synthesis of nanosize phosphors have been described. Four series of nanocrystalline Lu2O3:Eu3+ have been prepared for different composition of fuel (glutamic acid:glycine)(!) using the combustion method. The concentration of Eu(III) varied from 0.05 to 15wt% and the size of the nanoparticles covered the range 6-10nm. The size effect on optical properties of the phosphors have been investigated and correlated with the decay profiles of the Eu(III) emission. It has been proved that composition of the fuel influences the size of nanocrystallines, and in consequence their optical properties
