摘要：
We report the effective two-photon absorption-induced upconversion amplified spontaneous emission (ASE) in the cyano-substituted oligo(p-phenylenevinylene) 1,4-bis[1-cyano-2-(4-(diphenylamino)phenyl)vinyl]benzene (TPCNDSB) organic crystals. The material shows enhanced emission in the solid state (31% quantum yield in crystal) and efficient two-photon absorption. The ASE under the one-photon and two-photon excitation were observed. It is demonstrated that the organic crystals of TPCNDSB might be practically used as fluorescent materials for potential upconversion laser applications.
