Circularly polarized luminescence (CPL) can occur when either a luminophore or an ensemble of luminophores is chiral. The extent to which emissions are polarized is quantified in the same way it is for circular dichroism, in terms of the dissymmetry factor, also sometimes referred to as the anisotropy factor. This value is given by: where corresponds to the quantum yield of left-handed circularly polarized light, and to that of rig… WebCircularly polarized light is generated by: Passing plane polarized light through a birefringent plate (in the z-direction) which splits the light into two plane-polarized beams oscillating along different axes (e.g., fast along x and slow along y).
