Increase of doped ions concentration in the near-surface layer of Y2SiO5:Pr3+ nanocrystals was confirmed by modification of luminescence spectra with the heat treatment temperature. Relaxation of excess elastic stresses created by Pr3+ ions with volumes greater than volume of regular Y3+ ion was determined to be the main cause of observed effects. Theoretical estimations clearly confirm the preliminary predictions.
