Spectroscopic evidence of the multiple- site structure of Eu 3 + ions incorporated in ZnO nanocrystals

Abstract

Hexagonal Eu3+:ZnO nanocrystals were synthesized by a modified solgel method. By means of the site-selective spectroscopy at 10K, two kinds of luminescence sites of Eu3+ are identified. One site exhibits a long lifetime of D05 and sharp emission and excitation peaks, which are ascribed to the inner lattice site with an ordered crystalline environment. The other site associated with the distorted lattice sites near the surface shows a relatively short lifetime of D05 and significantly broadened fluorescence lines. The energy transfer from the nanocrystal host to Eu3+ confirms that Eu3+ ions can, to some extent, be incorporated into the ZnO nanocrystal.
