银纳米颗粒通过干法在玻璃中生成。首先通过电场辅助离子交换将银离子驱入玻璃中。随后在空气中退火导致在玻璃表面下形成银纳米颗粒。制备样品横截面的薄片。这种深度分布的可视化促进了对包含待预形成的银纳米颗粒的嵌入层的光学分析。我们观察到，有较窄的等离子体激元带靠近样品表面和较宽的等离子体激元带在较低的层。这是由于在样品表面附近形成了具有较低数密度的较大纳米颗粒，而在样品的深度处形成了具有较高数密度的略小纳米颗粒。
Silver nanoparticles are generated in glass by a dry process. First silver ions are driven into the glass by electric field-assisted ion exchange. Subsequent annealing in air led to the formation of silver nanoparticles beneath the surface of the glass. A thin slice of the cross section of the sample was prepared. This visualization of the depth profile facilitated optical analysis of the embedded layer containing silver nanoparticles to be preformed. We observed that there were narrower plasmon bands close to the sample surface and wider plasmon bands in lower layers. It is attributed to the formation of larger nanoparticles with lower number density close to the surface and slightly smaller nanoparticles with higher number density in the depth of the sample.
