Summary: This work investigates the properties of Ag-containing lead-boro-phosphate glasses in terms of structure, optics, refractive index dispersion, and shielding. It is found that Ag NPs precipitation occurs, as evidenced by XRD patterns and TEM images. The formation of Ag NPs leads to a depolymerization process and an increase in glass density, as well as a reduction in optical band gap energy. The optical performance of the glass is improved due to the formation of Ag NPs, making it suitable for various multi-functional optical devices.
