利用超瑞利散射(HRS)技术研究了纳米金颗粒悬浮液的非线性光学响应。在400 nm处测得的信号强度与1064 nm处的泵浦激光能量呈三次关系，表明测量到的信号是一个三阶非线性光学过程，即三光子激发荧光(3PF)。据我们所知，这是首次对胶体金纳米颗粒悬浮液进行3PF的实验观察。
Hyper-Rayleigh scattering (HRS) technique is used to study the nonlinear optical response of nanocrystalline gold particle suspensions. The signal intensity measured at 400 nm has a cubic dependence on the pump laser energy at 1064 nm, indicating that the measured signal is due to a third-order nonlinear optical process, namely three-photon excited fluorescence (3PF). To the best of our knowledge, this is the first experimental observation of 3PF for colloidal gold nanoparticle suspensions.
