LUMINESCENCE OF NANOMETRIC SCALE Y2SIO5-EU-3

We report what is to our best knowledge the first results of spectrosc opic properties of X(1)-Y2SiO5:Eu3+. The sample under UV or dye laser excitation at room temperature exhibits a strong orange-red fluorescen ce. By using selective excitation at low temperature, dissimilar photo luminescence (PL) spectra from different sites were obtained. The fluo rescence spectra, the excitation spectra of the fluorescence and the r adiative lifetime were studied.
