20090114880 | PHOSPHATE NANO PHOSPHOR AND METHOD OF PREPARING THE SAME - 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. | 05-07-2009 |
20100059713 | Preparation of Stable, Bright Luminescent Nanoparticles Having Compositionally Engineered Properties - A method is provided for preparing luminescent semiconductor nanoparticles composed of a first component X, a second component A, and a third component B, wherein X, A, and B are different, by combining B with X and A in an amount such that the molar ratio B:(A+B) is in the range of approximately 0.001 to 0.20 and the molar ratio X:(A+B) is in the range of approximately 0.5:1.0 to 2:1. The characteristics of the thus-prepared nanoparticles can be substantially similar to those of nanoparticles containing only X and B while maintaining many useful properties characteristic of nanoparticles containing only X and A. The nanoparticles so prepared can additionally exhibit emergent properties such as a peak emission energy less than that characteristic of a particle composed of XA or XB alone; this method is particularly applicable to the preparation of stable, bright nanoparticles that emit in the red to infrared regions of the electromagnetic spectrum. Luminescent semiconductor nanoparticles having exemplary properties are also provided. | 03-11-2010 |
