| 英文摘要 | We demonstrate a tunable broadband near-infrared absorber composed of VO2/Al2O3/ITO layers with a facile lithography-free method. Simulated and experimental spectra show that absorption bands with above 90% absorptance can be tuned from 1.62 similar to 2.42 mu m to 1.2 similar to 1.5 mu m by thermally induced VO2 phase transition. Furthermore, the absorber with VO2 in the intermediate state can yield a broadband perfect absorption over the wavelength range of 1.2 similar to 2.5 mu m. Besides high absorption performance can still be remained at the incident up to 70 degrees for both polarizations due to the presence of ultrathin layer of VO2 (lambda/52) in the absorber.
