Three-photon absorption and photoluminescence in films of liquid-crystal polymers with embedded CdSe/ZnS quantum dots

Three-photon absorption and photoluminescence in films of liquid-crystal polymers with embedded CdSe/ZnS quantum dots

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 intens...
