## Title

- title: Microscopic observations of RGB circularly polarized luminescence from solid
    microspheres with liquid crystalline molecular order
  title_type: original
  lang: en

## Description

- description: Micro-particles with an internal helical liquid crystalline (LC) molecular
    order serve as efficient and highly compact circularly polarized luminescence
    (CPL) emitters. However, the coupling between CPL emission and the interior LC
    molecular order remains poorly understood at the single particle level. Here,
    we synthesized microspheres from a LC monomer RM23 together with a fluorescent
    dye and a chiral additive (R/S-BPy) and investigated their CPL properties. Polarized
    optical microscopy and angle-dependent CPL observations at a single-particle level
    revealed randomly distributed one-handed helical domains in each sphere, leading
    to CPL emission with an average dissymmetry factor value |glum| of 0.05 regardless
    the observation angle. The color of the CPL emission is tunable in the range of
    450 to 700 nm by varying the fluorescent dyes doped in the spheres.
