<p>Provided is a fluorescent powder of halogen-silicate containing nano-metal particles with the formula of CaX 2 ·y(Ca 1-a-b Eu a Mn b O)·SiO 2 :zM, wherein X is fluorin or / and chlorine, y is 1 or 2, z is molar ratio of nano-metal particles and fluorescent powder CaX 2 ·y(Ca 1-a-b Eu a Mn b O)·SiO 2 , 0<z‰¤1×10 -2 , 0<a‰¤0.3, 0‰¤b‰¤0.3. The method for preparing the fluorescent powder is also provided. For the surface plasma resonance effect occurring on the surface of the nano-metal particles, the fluorescent powder has stronger luminous intensity. The preparation method is simple to operate, no pollution, easy to control, easy to produce in industry, and can be widely used in the preparation field of fluorescent powder.</p> |
