Dynamic infrared emissivity regulators, which can efficiently modulate radiation beyond vision, have emerged as an attractive technology in the energy and information fields. The realization of independent modulation visible spectra is a challenging important task for application dynamic regulators fields smart thermal management multispectral camouflage. Here, we demonstrate electrically controlled regulator that achieve while maintaining high transparency (84.7% at 400-760 nm). show degree regulation (0.51 3-5 μm, 0.41 7.5-13 μm), fast response ( < 600 ms), long cycle life > 104 cycles). attributed to modification carrier concentration surface depletion layer aluminum-doped zinc oxide nanocrystals. This transparent provides opportunities applications such on-demand management, displays, adaptive
