Abstract

Strontium chloroapatite nanocrystals doped with trivalent europium ions were prepared by an aqueous colloidal method. The mean diameter of the crystal was found to be&3 nm by transmission electron microscopy, although, for the most part, they were agglomerated. The X-ray di!raction patterns show that the lattice constants of nanocrystals are contracted by&2% compared to the corresponding bulk counterpart, and also that they further decrease by annealing at 200}3003C. The fuorescence spectrum of nanocrystals exhibited blue shifts of both the 5D0}7F2 transition and the charge transfer excitation band, and an apparent enhancement in the strength of the hypersensitive 5D0}7F2 transition.
