摘要: A color conversion filter contains at least one kind of squarylium dye that radiates fluorescence light, has a wavelength capability, absorbs light in an unneeded region, preferable and does not allow decrease brightness, thus is for light-emitting devices, photoelectric devices the like. Specifically, absorption having high intensity range 570 to 600 nm, use 780 nm.
