1. A system comprising:
an electroactive substrate;
a plurality of nanoparticles deposited in communication with the electroactive substrate; and
a processor configured to manipulate a shape of the electroactive substrate between a unactuated mode and an actuated mode to change an absorption band or an emission band of the plurality of nanoparticles,
wherein when the electroactive substrate shape is manipulated, the absorption band or the emission band of the plurality of nanoparticles is changed to tune the system for a radiative cooling based on a current dominating wavelength.
