Abstract: A process is disclosed for cooling a material that includes semiconductor nanoparticles in matrix material by anti-Stokes up-conversion. The semiconductor nanoparticle matrix is irradiated by a laser with a photonic wavelength matched to the anti-Stokes photoluminescence of the semiconductor nanoparticle bandgap. The semiconductor nanoparticles absorb the laser photon and phonons (heat) from lattice vibrations to photoluminescence photons with higher energy than the photon that were absorbed. A net cooling effect is generated from the lower energy and lower temperature in the material after anti-Stoke up-conversion.
