A content of Al in the phosphor is set be to within a range between 0.001 mol and 0.3 mol. The range permits a variation in luminance of the phosphor to be within .+-.30% and initial luminance of the phosphor to be significantly increased, resulting in the phosphor being suitable for use for a fluorescent display device.

摘要： A method for preparing a gallium nitride phosphor which is capable of emitting light at luminance increased to a degree sufficient to permit the phosphor to be practically used. A dopant compound containing elements reacted with H2 and gasified by heating is arranged on an upstream side in a calcination oven in which NH3 is flowed and a matrix element compound is arranged on the downstream side therein, resulting in calcination of the compound being carried out. This permits GaN to be surrounded with ammonia and the dopant during the calcination, so that the GaN phosphor may be fully doped with the dopant.

摘要： A dispersion of carbon nanoparticles is prepared by monodispersing carbon nanoparticles in water droplets of a reverse micelle solution in which the water droplets are coated with amphiphilic molecules and dispersed in an organic solvent. In a method of preparing the dispersion of carbon nanoparticles, carbon nanoparticles and a monodispersion function material, e.g., ammonia, for imparting a polarity to surfaces of the carbon nanoparticles are added to the reverse micelle solution. The solution is then stirred, so that the carbon nanoparticles whose surfaces have the polarity are monodispersed in the water droplets of the reverse micelle solution. Further, a metal alkoxide is added to the solution and then stirring them, so that the surfaces of the carbon nanoparticles are coated with oxide of the metal.

摘要： Ultradispersed ones of primary particles of nanometer-sized carbon are obtained by applying a wet-type milling method and/or a wet dispersion method to an aggregate structure of the primary particles to overcome van der Waals forces, by which forces the primary particles are held together to form the aggregate structure, whereby the ultradispersed primary particles are obtained in a colloidal dispersion on a large-scale basis at low cost without using any additive. In a method of manufacturing the ultradispersed primary particles, the wet-type milling method is carried out in a ball mill, preferably in combination with a high-energy ultrasonic-wave process carried out in a dispersing medium such as pure water, whereby a colloidal solution or slurry with a low-concentration of the primary particles ultradispersed in the dispersing medium is obtained.
