The single & two photon excited fluorescence property and crystal structure of a substituted stilbene-type compound trans-4-diethylamino-4(-bromostilbene (DEABS) has been reported. The results indicate that this compound has strong two photon excited blue fluorescence at 440 nm when the 700 nm laser was used as the pump source.
