Circularly polarized emission
WebApr 14, 2024 · Circularly polarized fluorescence emitted from the sample should be collected by the photo-detector placed in the angle of 90° or 180° toward the extinction direction. The light from the sample first passes through a PEM and polarizer, and is then passed through a monochromator and detected by a detector. WebStimulus-responsive materials that display circularly polarized luminescence (CPL) have attracted great attention for application in chiral sensors and smart displays. However, due to difficulties in the regulation of chiral structures, fine control of CPL remains a challenge. ... Specifically, CPL emission can be switched reversibly by ...
