Abstract
A light filtering material including at least one matrix material; and semi-conductive nanoparticles which are dispersed in the matrix material. The light filtering material has: a local maximum absorbance of highest wavelength in the range from 350 to 500 nm, the local maximum has an absorbance value Amax for a wavelength λmax; a value of 0.9Amax for a wavelength λ0.9, λ0.9 being greater than λmax; a value of 0.5Amax for a wavelength λ0.5, λ0.5 being greater than λ0.9; and |λ0.5−λ0.9| is less than 15 nm.
