(a) Transmittance spectra of UV absorbing film as a function of wavelength with different center wavelengths (i.e., , 500, 550, and 600 nm). The inset highlights the visible region. (b) Electric field intensity distribution of the designed film with a center wavelength of 550 nm at UVB ( nm), UVA ( nm), and visible ( nm), respectively. (c) The normalized electric field intensities versus the position of (b) are presented as a line graph.
