When Ag-doped white glasses are treated in a hydrogen atmosphere, silver nanoparticles can form at 250 ℃ in 2 min, and the mean particle size is smaller than that obtained from thermal treatment in air, which induces a blue shift of surface plasma resonance absorption.

  • 在氢气气氛中,在250℃热处理2min,即可在玻璃中形成大量Ag纳米颗粒,颗粒尺寸小于空气中高温热处理样品的尺寸,从而引起表面等离子体共振吸收峰发生蓝移。
