GREEN FLUORESCENT CERAMIC MATERIAL, PREPARATION METHOD THEREFOR AND USE THEREOF
A green fluorescent ceramic material, a preparation method therefor and the use thereof, are applicable in the field of fluorescent ceramics for LED lighting. The chemical constitution of the green fluorescent ceramic material is graphene-Y3-x-yAl5O12:x Ce3+, y Lu3+, with 0.0001≤x≤0.1, and 0.01≤y≤2.9; and the mass percentage of graphene is less than 0.5 wt % but is not 0 on the basis of the total weight of the green fluorescent ceramic material. The green fluorescent ceramic material has the characteristics of a high heat conductivity, a good heat dissipation property, and a controllable light-emitting wavelength within a range of 490-540 nm; and same is suitable for use as an LED encapsulating material.
