Abstract:In this paper, we studied nonlinear absorption of infrared (IR) (1250 nm) femtosecond pulses and visible photoluminescence (PL) excited by them in liquid-crystal (LC) polymer films with embedded CdSe/ZnS core-shell type quantum dots (QDs). The dependence of nonlinear transmission on incident intensity indicated three-photon absorption in the films, with the three-photon absorption coefficient for the QD-LC polymer composite comparable with the one for bulk CdSe. The spectrum of PL excited by IR pulses coincide… Show more
