Fabrication procedure of nanocrystalline Lu2O3:Eu powders from organic–inorganic emulsion is presented and the behavior of the precipitate upon heat-treatment is analyzed. It is proved that heating at 800–850 °C converts the raw material into Lu2O2SO4:Eu, which decomposes further to Lu2O3:Eu when heated at 1000 °C or above. Research with synchrotron radiation revealed that free exciton is able to transfer effectively its energy to Eu3+ ions in Lu2O3:Eu nanosized powder, which is in contrast to the findings for micron-sized ceramics of the same composition.
