SERS effect of aggregation of silver nanoprisms induced by 785 nm laser

  • 摘要: 为实现表面增强拉曼散射(SERS)光谱的强信号快速检测分析,报道了通过785 nm 诱导银纳米三角片(AgNPRs)聚集的方法。采用配体辅助化学还原法制备了AgNPRs,其边长约为80 nm,表面等离子体吸收峰出现在约774 nm处,对785 nm光产生有效吸收。在785 nm光辐照下,AgNPRs逐渐聚集,对巯基苯甲酸的SERS信号逐渐增强,其源于AgNPRs吸收的光转化为热而引起的AgNPRs聚集。其增强因子高达109。为快速获得强SERS信号,激发光功率需大于250 mW。
