Abstract

Trans-4-(N, N'-dimethyl amino)-4′-(N-hydroxyethyl-N'-ethyl amino) stilbene (DMAHAS) has been synthesized and characterized by 1H NMR spectra, ER spectra and elemental analysis. Linear absorption, single-photon induced fluorescence and two-photon induced fluorescence were experimentally studied. This new dye has a moderate two-photon absorption cross-section of σ 2 = 0.91 × 10–46 cm4 · s/photon at 532 nm by using an open aperture Z-scan technique. The result indicates that DMAHAS shows a strong two-photon induced blue fluorescence of 432 nm when pumped with 800 nm laser irradiation.
