We report on the 3D precipitation, using a direct laser writing approach, of highly fluorescent silver clusters in a Eu 3+-doped silvercontaining zinc phosphate glass. Micro-spectroscopy of fluorescence emission shows the ability to continuously adjust the local trichromatic coordinates in the CIE chromaticity diagram between red and white colors, thanks to the laser-deposited dose and resulting tunable combination of emissions from Eu 3+ and silver clusters. Moreover, CW and time-resolved FAST-FLIM spectroscopies showed a significant enhancement of the fluorescence emission of Eu 3+ ions while being co-located with UV-excited laser-inscribed silver clusters. These results demonstrate the ability to perform efficient resonant non-radiative energy transfer from excited silver clusters to Eu 3+ , allowing such energy transfer to be highly localized on demand thanks to laser inscription. Such results open the route to 3D printing of the rare earth ions emission in glass.< Réduire
