Several surface plasmon absorption bands are observed due to the disk shape of these particles. In the time-resolved experiments, the time dependence of the bleach resulting from femtosecond pulsed excitation is studied. On the 1-3 ps time scale, a decay resulting from electron-phonon relaxation is observed. On a longer time scale (&gt;20 ps), a rise father than a further decay of the bleach intensity is observed. This is shown to result from the formation of a thermal lens due to the induced thermal gradients produced from heating the organic solvent by the phonon-phonon relaxation processes of the photoexcited nanodisks.</style></abstract><accession-num><style face="normal" font="default" size="100%">WOS:000220997300018</style></accession-num><notes><style face="normal" font="default" size="100%">Maillard, M Pileni, MP Link, S El-Sayed, MA</style></notes><electronic-resource-num><style face="normal" font="default" size="100%">10.1021/jp049943z</style></electronic-resource-num></record></records></xml>
