Circularly polarized light exhibits promising applications in future displays and photonic technologies. Traditionally, circularly polarized light is converted from unpolarized light by the linear polarizer and the quarter-wave plate. During this indirectly physical process, at least 50% of energy will be lost. Circularly polarized luminescence (CPL) from chiral luminophores provides an ideal approach to directly generate circularly polarized light, in which the energy loss induced by a polarized filter can be reduced. Among various chiral luminophores, organic micro-/nano-structures have attracted increasing attention owing to the high quantum efficiency and luminescence dissymmetry factor (glum).
