Luminescence properties of nanocrystalline europium titanate Eu2Ti2O7

Original language description

Nanocrystalline europium titanate Eu2Ti2O7 with tailored structural properties was prepared by a sol-gel approach. Structural properties of prepared nanocrystals were correlated to the steady-state and time-resolved luminescence spectroscopy of europiumions incorporated within formed nanocrystals. The formation of nanocrystalline Eu2Ti2O7 raised up the existence of two inequivalent positions of Eu3+ ions. Eu3+ ions displaced in highly symmetrical positions within the pyrochlore lattice provided low intensity luminescence and lifetime shorter than 10 mu s. Eu3+ ions displaced in asymmetrical positions on the surface of formed nanoparticles provided lifetimes on the level of 50 mu s. Number of Eu3+ ions displaced in asymmetrical positions was decreasedaccording to increase size and crystallinity of formed nanocrystals. The presented results provide fundamental information about the influence of the structure and the morphology of formed nanocrystals to their luminescence properties
