Precipitation of silver nanoparticles (Ag-NPs) can occur in a silver-doped lanthanum borogermanate glass matrix, either under thermal annealing or femtosecond direct laser writing (DLW). Macroscopic transmission and localized µ-fluorescence emission spectra provide typical plasmon resonance behavior of Ag-NPs. Annealing leads to the spatially random homogeneous creation of small NPs at low concentrations, while DLW shows higher and broader plasmon peaks, proving highly concentrated 3D localized structured NPs. DLW at high fluencies shows photo-induced dichroism, potentially giving access to 3D dichroic photonic responses.Read less <
