Abstract
A photonic band gap structure of (SiO2/TiO2)5 with Ag system for energy efficient film was proposed theoretically and experimentally. The calculated transmittance spectra show high transmittance in the visible range, but ultra-low transmittance in the wavelength ranges of ultraviolet and infrared. Besides, the effects of the incident angle and two opposite directions on the optical characteristics were studied. The results demonstrate that the structure can simultaneously satisfy the demands of lighting and heat insulating as energy efficient window film. The cross-section morphology indicates that the sample has good periodicity in accordance with the design, whereas the experimentally measured transmittance spectra are well matched with the theoretical calculation.
