Switchable optical materials,which possess reversible light transmission in response to external stimuli are of wide interest for potential applications such as energy efficient windows,roofings,and skylights that can either transmit or block light.So far,most literatures have demonstrated switching between two states,color and transparency,color and whiteness,and whiteness and transparency.Few can switch between all three states.
