Abstract:
A composition and a wavelength converter are provided. The composition includes at least: quantum dots having an emission peak wavelength in a visible light region; and quantum dots having an emission peak wavelength in an ultraviolet region or in a near-ultraviolet region. The wavelength converter includes, in a polymer: quantum dots having an emission peak wavelength in a visible light region; quantum dots having an emission peak wavelength in an ultraviolet region or in a near-ultraviolet region; and an oxide formed by oxidizing at least a part of the quantum dots having an emission peak wavelength in an ultraviolet region or in a near-ultraviolet region.
