摘要: Abstract Femtosecond (fs) laser writing of two-dimensional microstructures (waveguides) is demonstrated in bulk phosphate glasses doped with silver ions. Silver-content and silver-content niobium–phosphate high concentration oxide 55 mol% were used as samples for fs writing. The chemical network structure the synthesized analyzed through Raman spectroscopy was found to be strongly sensitive Nb incorporation. It that direct process enables not only reorganization glass network, but also formation color centers nanoparticles are revealed appearance luminescence signal plasmon absorption. NPs' more efficient Nb-phosphate glass, while preferably formed glass.
