The mechanism of optically controllable scattering is the light‐induced dissolution of poly(N‐vinylcarbazole) (PVK) into dye‐doped liquid crystals, which reforms the disordered liquid crystal (LC) distribution into multiple and micron‐sized LC domains. The generated scattering can be switched back to the original one by particular thermally induced phase separation.
