TL;DR
This study investigates how the polarization of light affects exciton-plasmon-photon conversion in silver nanowires coupled with quantum dots, revealing polarization-dependent fluorescence enhancement and emission directionality.
Contribution
It demonstrates the polarization dependence of exciton-plasmon-photon conversion in silver nanowire-quantum dot structures, highlighting the correlation between fluorescence enhancement and light polarization.
Findings
Fluorescence enhancement depends on the angle between excitation polarization and nanowire.
Emission polarization aligns predominantly with the nanowire direction.
Conversion efficiency varies with polarization orientation.
Abstract
Polarization dependence of the exciton-plasmon-photon conversion in silver nanowire-quantum dots structure was investigated using a scanning confocal microscope system. We found that the fluorescence enhancement of the CdSe nanocrystals was correlated with the angle between the excitation light polarization and the silver nanowire direction. The polarization of the emission was also related with the nanowire direction. It was in majority in the direction parallel with nanowire.
