Nano fluorescent ceramic as well as preparation method and application thereof
The invention provides a nano fluorescent ceramic and a preparation method and application thereof, the molecular general formula of the nano fluorescent ceramic is A3-xB5O12: xCe, in the formula, the element A comprises at least one of Y, Lu, Gd and Tb, the element B comprises at least one of Al, Mg and Si, the content of Lu in the element A is greater than 50%, the content of Al in the element B is greater than 50%, the element Ce substitutes a part of the element A and occupies lattice sites of the element A, and the content of Mg in the element B is greater than 50%. As a light-emitting center, 0 lt; x is less than or equal to 0.015. The nano fluorescent ceramic has the advantages of being small in particle size, high in efficiency, good in luminous efficiency, high in light intensity, adjustable in color, long in service life and the like, the prepared nano fluorescent ceramic has high heat conductivity and can be effectively excited by blue laser, scattering of incident laser can be enhanced through nano-sized crystal grains, the light conversion efficiency of the blue laser can be improved, and the light conversion efficiency of the blue laser can be improved. And a high-brightness illumination light source is obtained. The nano fluorescent ceramic and the preparation method can be widely applied and developed in the field of laser illumination.
