Abstract: We report photoluminescence in bulk chloride photo-thermo-refractive glass under irradiation with femtosecond laser pulses. The fluorescence originates from the bleaching of silver nanoparticles precipitating in the glass. Similarly to the conventional process of the femtosecond… read more here.

Abstract: In the present research, a new class of bromine-containing photo-thermo-refractive (PTR) glass in which the UV irradiation and subsequent heat treatment cause the precipitation of silver nanoparticles with a shell consisting of silver bromides is… read more here.
