Nonlinear-Optical Response of Prussian Blue: Strong Three-Photon Absorption in the IR Region.
The nonlinear-optical properties of Prussian Blue nanoparticles have been evaluated with the use of femtosecond Z-scan measurements in the 1350-1750 nm range. This well-known inorganic pigment having interesting magnetic and electrochemical properties was found to be an efficient near-IR three-photon absorber. The maximum of the effective three-photon cross section is as high as 4.5 × 10-78cm6s2at 1375 nm. By a comparison of the three-photon molar-mass-normalized merit factors, σ3/M, we show that this material is a competitive multiphoton absorber, especially in comparison to semiconductor quantum dots.
