The open aperture z-scan technique was employed to measure the two-photon absorption coefficient of this material in solution over a range of concentrations in chloroform at 800 nm. We measured the two-photon absorption cross-section to be 197 × 10-50 cm4 s photon -1. We have also demonstrated strong up-converted emission in solutions of the same molecule highlighting the potential of this material for applications such as up-conversion and two-photon fluorescence microscopy.Keywords: Absorption; Benzene; Concentration (process); Fluorescence; Nonlinear optics; Photons; Spectroscopic analysis; Organic dye; Two-photon absorption; Up-conversion; Z-scan; Dyes Nonlinear optics; Organic dye; Two-photon absorption; Up-conversion; z-scan20052015-12-12
