摘要

研究了银纳米粒子在含银磷酸盐玻璃激光写入微米波导中的沉淀过程。在精心设计的激光写入制度和可控的写入速度下，可以调整表面等离子体共振带的位置和形状，这反映了银NPs从球形到球形的形状变化。该方法可用于控制玻璃-金属复合材料的各向异性。

Ultrafast Laser-Induced Precipitation and Reshaping of Silver Nanoparticles in Phosphate Glass

We studied the precipitation process of silver nanoparticles (NPs) in the micron-sized waveguides laser-written in silver-containing phosphate glass. At the elaborated laser-writing regime and controllable writing speed, it is possible to tune the position and shape of the surface plasmon resonance band which reflects the change in the shape of the silver NPs from spherical to spheroidal. The proposed approach can be applied to control the anisotropy of the glass-metal composite materials.
