The unique role of bromine in NaF crystallization of photo-thermo-refractive glass

Photo-thermo-refractive (PTR) glass generates a refractive-index modulation through photothermally induced NaF nanocrystallization, making it essential for volume Bragg gratings. The halide co-dopant determines how silver nanoparticle templates (Ag NPs@AgX, X = Cl, Br, I) steer N...
