Abstract
Results are presented on the the two-photon absorption and fluoroscence properties of a new molecular crystal based on (E)-(E)-4-(p-N,N-dimethylaniline)-1-cyano-1-di(ethoxy)phosphinoylbuta-1,3-diene (DCP). This material shows a two-photon-induced fluorescence when excited in the infrared, in powder ∼6 times that obtained from a [2-[2-[4-dimethylaminophenyl]ethenyl]-6-methyl-4H-pyron-4-ylidene] propanedinitrile powder excited at 1.064 μm, and ∼50 times that of a 1-cm-long Rhodamine 640 solution (2 mM in methanol). Pulsed photoacoustic spectroscopy has been used to characterize the two-photon absorption band of the crystalline state. A high two-photon absorption coefficient, β = 15 cm/GW, is reported, and an energy-conversion yield of 2.0% (incoherent fluorescence) was obtained in DCP monocrystal in single-pass beam configuration. Finally, a correlation is shown between the polarization of the excitation radiation and the crystalline structure of the material.
