Fabrication of Ag-doped Na₂O-B₂O₃-SiO₂ Glass by Sol-gel Method

A sol-gel process to fabricate Ag-doped Na₂O-B₂O₃-SiO₂ glass was presented. The flow sheet for experiment was described. X-ray diffraction and infrared absorption spectra were used to determine the structure and its change during fabrication. The optical absorption spectra and TEM were used to testify the existent of Ag colloid particles. The results show that the glass made by the sol-gel method has the same structure as that made by the molten method, and Ag particles with a distribution of sizes have been obtained after well-controlled heat treatment. This method can be used to produce color glass and its product was also the raw material of other devices.
