Three-Dimensional High Spatial Localization of Efficient Resonant Energy Transfer from Laser-Assisted Precipitated Silver Clusters to Trivalent Europium Ions

We report on the 3D precipitation, using a direct laser writing approach, of highly fluorescent silver clusters in Eu3+-doped silver-containing zinc phosphate glass. Micro-spectroscopy fluorescence emission shows ability to continuously adjust local tri-chromatic coordinates CIE (Commission Internationale de l’Éclairage) chromaticity diagram between red and white colors, thanks laser-deposited dose resulting tunable combination emissions from Eu3+ clusters. Moreover, continuous-wave time-resolved FAST-FLIM spectroscopies showed significant enhancement ions while being co-located with UV-excited laser-inscribed These results demonstrate perform efficient resonant non-radiative energy transfer excited Eu3+, allowing such be localized demand inscription.
