PRODUCTION OF INORGANIC MICROFIBER AND INORGANIC MICROFIBER

摘要

PROBLEM TO BE SOLVED: To provide a light emitting material which is capable of emitting visible light at room temp. and is easily applicable to devices. ;SOLUTION: For example, amorphous silicon hydride (a-Si:H) is irradiated with a freer electron laser beam of 7.85μm in the wavelength to be absorbed in the three electron bonds in the a-Si:H, 0.2 to 2GW/cm² in pack power density and 20 to 24mW/cm² in average power density in an atmosphere contg. carbon, nitrogen and/or oxygen at room temp. The production is made possible in a short time and industrialization is easy. The radius of the quantum point of the silicon of the inorg. microfiber mainly consisting of the silicon and silicon is 2 to 3nm. The possibility of obtaining the light emitting material which emits light in a visible region at room temp. and is variable in the light emission wavelength when the size of the quantum point is controlled is conceivable. The application to the optical waveguides and optical modulation elements of optical integrated circuits is expected.;COPYRIGHT: (C)1998,JPO
