Abstract

We have demonstrated the co-doping of silver ions and Bi3+ in glass allowing creation of 3D structures with tuning luminescence properties from the visible to the near IR with fs DWL. The tunable luminescence arises from the fs laser triggering both the photochemistry of silver ions and the photo-redox reaction of Bi3+ forming low valence Bismuth ions (Bi2+ red emitter and Bi+ near IR emitter). Confocal hyper-spectral lifetime-resolved imaging revealed the shortening of the fluorescence lifetime of silver clusters in the presence of Bismuth revealing the energy transfer mechanism from silver clusters to Bi+.
