Abstract :
Summary form only given. We measured the emission temporal profiles of a PPV derivative, poly[2,5bis(cyclohexylmethoxy)-1,4-phenylenevinylene] (PDCKPV), film with an excitation density of 1 GW/cm/sup 2/ by using fluorescence upconversion technique with femtosecond pump and gate pulses at 400 and 800 nm, respectively.
