A down-converted light emitting combination that generates a visible light when an ultraviolet light is incident is provided. The down-converted light emitting combination includes a first structure made of a first material that generates a visible light of a first color when an ultraviolet light of a first wavelength range is incident and a second structure made of a second material that generates a visible light of a second color different from the first color when the ultraviolet light of a second wavelength range different from the first wavelength range is incident, and the first material and the second material have different emission colors and distributions of intensities of the visible lights generated depending on a wavelength of the incident ultraviolet light.
