    摘要： Provided is a phosphate nano phosphor with a mean particle diameter of 100 to 3000 nm. Also provided is a method of preparing a nano phosphor, the method comprising: dissolving two or more species of metal precursor compounds in water, and then adjusting the pH to prepare an aqueous solution of pH 4-10; coprecipitating the aqueous solution by mixing with a phosphate precursor aqueous solution with the pH adjusted to 7-12; and redispersing the particles obtained from the coprecipitation in water or polyol solvent, and then heat treating the particles. The phosphate nano phosphor according to the present invention has superior light emission efficiency compared with conventional nano phosphors.

    摘要： A fluorescent lamp utilizing a four component phosphor combination is provided producing efficient white color illumination at a lower cost than conventional phosphor coatings of the same type. A lamp color temperature of approximately 3500.degree. K. is produced with a blend containing two strontium apatite phosphors, one strontium orthophosphate phosphor and a calcium haloapatite phosphor. The strontium phosphors are blended in weight proportions to match the white color emission point of the calcium haloapatite phosphor component in said blend.
