Abstract

Nanocrystal Y

:Eu with different concentration of Eu and grain size from 5nm to 80nm were prepared by combustion method. Their excitation spectra

emission spectra

the lifetime and integral intensity of different samples were measured and compared. It is found that as the grain size decrease

the absorption of charge transfer states is red-shifted from 239 to 250nm

the emission spectra and excitation spectra show a band-like structure with increasing strength in addition to the peaks as in bulk Y

:Eu material

which is not result from amorphous effect

the life time of 611nm emission decreases in the same magnitude

and the quenching concentration increases. The mechanism of these phenomenon is revealed by crude analysis.
