Outline of Final Research Achievements

In this study, we have systematically investigated the detailed mechanism of LSPR-enhanced-absorption, emission and chiroptical signals by tuning of chiroptical properties through changing the size, shape and species of the NP cores etc. We have developed a new method utilizing the phenomenon of plasmon resonance to amplify emission via circularly polarized luminescence. The optical properties of a molecule complexed with silver nanoparticles (AgNPs@SiO2, etc.) were enhanced by the excited LSPR electric filed. This excitation of AgNPs@SiO2 surface plasmon resulted in |gabs| and |glum| values that were several times greater than in the unbound AgNPs. This new technique has the potential to be used in many chemical and biological applications that necessitate highly sensitive CPL measurements.
