Investigations of the heat treatment influence on the luminescence of nanocrystalline ZrO₂ + 10 mol.% Eu were performed. Nanopowder with average crystallite size of  5 nm and Specific Surface Area (SSA) of 160 m²/g was synthesized using hydrothermal-microwave synthesis method. Material was heated in air at temperature in range 400-850^oC during one hour. The microstructure and luminescence characteristics were done. We ascertained that grain growth and decrease of SSA occurred in the samples annealed at temperature higher than 400^oC. The most significant changes were observed for material heated at 850^oC when average crystallite size increased to 12 nm and SSA decreased to 35 m²/g. We established that microstructure of the powders influenced their optical properties; the higher was  annealing temperature, the lower was intensity of europium luminescence.
