Abstract
Double core-shell fluorescent materials and preparation methods thereof are provided. The double core-shell fluorescent materials include inner core, inner shell coating the inner core and outer shell coating the said inner shell. The inner core is metal particle and the chemical constitution of the inner shell is silicon dioxide. The outer shell is fluorescent powder represented by the following chemical formula: (R, Eu)O, wherein R is Y, Gd or combination thereof, 0.02≦x≦0.1. The double core-shell fluorescent materials with uniform and stable luminous effect not only increase luminous intensity, but also decrease usage amount of fluorescent powder by using metal particle as inner core.
