<正> A new method of preparation of irradiative material by using rare earth as luminophor and inorganic powder as base nucleus was presented. Rare earth was used to make colloid, which was mixed with base nucleus solution, where deposition/attachment reaction took place and rare earth was adhered onto the surface of base nucleus, hence yielding a new rare earth encapsulated irradiative material. Fluorescent spectrum analysis shows that this material possesses two emission peaks, one within 400-500 nm and the other within 580-700 nm, reflecting the luminous characteristics of original rare earth material.
