An all-round improvement of the switchable mirror characteristics of any rare earth metal system can be achieved by utilizing two characteristics of nanoparticles: the size-dependent blue shift in the absorption edge and large surface area. Gd nanoparticles show better color neutrality in comparison with polycrystalline, alloy, and multilayer films, and also exhibit increased optical contrast and faster response time than polycrystalline films.
