Abstract: PROBLEM TO BE SOLVED: To obtain a fluorescent substance containing fullerene as a substrate and a specific auxiliary substance, enhanced in luminous strength and useful for light sources of visible and infrared spectrophotometers. SOLUTION: This fluorescent substance is composite laminate of (A) fullerence layer having one or more layers (preferably fullerence which is C60) with (B) an auxiliary substance layer having one or more layers. The component B is selected from a metal, a semi-metal, a metal compound, a semi-metal compound and a mixture thereof. A preferred example of the component B includes silicon, germanium, tin oxide, titanium oxide or indium oxide. Total thickness of the layer of the component A is preferably 500nm to 500μm and total thickness of the layer of the component B is preferably 10nm to 100μm and the component B is preferably 0.5-10wt.% based on total amount of the components A and B.

Abstract: PROBLEM TO BE SOLVED: To improve the luminous intensity by applying a mechanical stress to a fullerene provided with such a feature that it emits white light when irradiated with argon laser beams or when an electric current flows therethrough. SOLUTION: A fullerene C60 film with a thickness of 1-10μm is formed by vacuum deposition on a base plate comprising, e.g. fused silica, a slide glass, Pyrex, a silicon wafer, an alkali halide, a plastic, or a ceramic. A mechanical stress is applied with a sharp edge of, e.g. a knife, a needle or a glass cutter to the formed C60 film to produce scratches on the surface thereof. The C60 film with scratches is irradiated with argon laser beams having a wavelength of 514.5nm to 30mW or allowed to pass an electric current therethrough to cause the emission of white light having a vary wide wavelength distribution (600-4,500nm) over a visible light to infrared region, with a light intensity peak in a wavelength region from 1,500 to 2,000nm.

Abstract: PROBLEM TO BE SOLVED: To generate a strong luminescence having an emission spectrum of a wide range by laminating one or more fullerene layer and one or more auxiliary substance layer on a base material and forming a metal, metalloid, metal compound, metalloid compound and their mixture by sputtering as an auxiliary substance. SOLUTION: One or more fullerene layers and one or more auxiliary substance layers are laminated on a base plate and a metal, metalloid, metal compound, metalloid compound or their mixture is formed by sputtering as an auxiliary substance. As the auxiliary substance, a silicon, germanium, tin oxide, titanium oxide, indium oxide, silicon oxide, aluminum oxide, zinc oxide, silicon nitride, boron nitride or the like is preferable. The fullerene layers and a plurality of the auxiliary substance layers are preferably alternately laminated preferably in view of luminescence. For example, an argon laser beam having a wavelength of 514.5 nm of a luminophor is emitted to its surface to emit a white light having a spectrum of a wavelength of 650 nm or more.
