Fig. 1: Concurrently amplified dissymmetry factor glum and upconversion emission from plasmon-micelle composites in aqueous solution.
a Under the excitation of UV light, the chiral emitter shows prompt CPL with a glum value around 1.0 × 10−3. When chiral emitter/sensitizer/CTAB micelles assemble into upconverted micelles, the high-frequency UC-CPL can be obtained under excitation with low-frequency light. The upconverted micelles exhibit amplified glum values between 1.0 × 10−3 and 1.0 × 10−2. Furthermore, plasmon-micelle composites that are formed by upconverted micelles and plasmon nanoparticles through electrostatic interaction can produce plasmon-enhanced UC-CPL, in which upconverted emission intensity and glum value (>1.0 × 10−2) are enhanced simultaneously. b Illustration of multiple photophysical processes in plasmon-assisted TTA-UC system.
