WebJun 13, 2024 · Energy harvesting coil for circularly polarized fields in magnetic resonance imaging. Pavel Seregin, Oleg Burmistrov, Georgiy Solomakha, Egor Kretov, Nikita … 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…
