Abstract
The present invention is a yellow-green phosphor material with a high luminescence intensity. The present invention is suitable for excitation by ultraviolet or blue light. The phosphor material is made of a phosphate compound with a chemical formula of LiZn1-xPO4:Mx(0<x<0.2). The host lattice is LiZn1-xPO4 and the luminescent center is Mx, which is a transition metal element. The present invention is easily and fast fabricated for mass production and has a fine color purity and a good thermal stability.
