Abstract: Disclosed is a wavelength conversion film including at least two or more dyes and absorbing irradiation light to emit light at a longer wavelength than that of the irradiation light. The wavelength conversion film includes a first dye having a maximum absorption wavelength in a red light region, and a second dye absorbing excitation energy of the first dye to emit light in a near infrared region.

Abstract: Provided is a light emitting member that emits near-infrared light, containing a surface light source that emits at least red light and a wavelength conversion film that converts visible light of the surface light source into near-infrared light, wherein the light emitting member has a maximum emission wavelength in the wavelength range of 700 to 1500 nm.
