Emission color stability, color rendering, and low cost, the white LED light conversion material trends, the development of the chemical properties of the luminous efficiency white LED with a single near-UV LED chip multi-colored light conversion material consisting of white light source single multi-color phosphor has a very important significance. In this paper, the different luminescence centers generated by the activator ions in the matrix material and the energy transfer between them, using high temperature solid state synthesis SrMg 2 (PO 4 ) 2: Eu 2 , Mn 2 , Ba 2 Ca (BO 3 ) 2: Ce 3 Mn 2 and Ca2BO3Cl: the Ce 3 the of Eu 2 three systems of a single multi-color phosphor, and they luminous performance, energy transfer properties and colorimetric performance analysis and obtained the following results: (1) SrMg 2 (PO 4 ) 2: Eu 2 , Mn 2 with blue and red double-emission band in the near ultraviolet excitation the of Eu 2 to Mn 2 resonance energy transfer, the relative strength of the two emission peaks can be controlled through the regulation of Eu 2 of Mn 2 relative concentration, the excitation spectrum of the near-ultraviolet match the LED chip, and has a lot of potential. (2) Ba 2 Ca (BO3) 2: Ce 3 , Mn 2 , Ce , 3 occupy Ba the 2 [Ce 3 (1)] and the of Ca 2 [the Ce 3 (2) of the Sites of, produce blue and green light-emitting Mn 2 produces red emission, while the existence of Ce 3 (1) → Mn 2 Ce 3 (1) → of Ce 3 (2), the Ce 3 (2) → Mn 2 , and Ce 3 (1) → Ce 3 (2) → Mn 2 four energy transfer process, by regulation of Ce 3 and Mn 2 the relative concentrations of, respectively, obtained in the 345nm and 395nm excitation white light emission, there are hopes to become a near-ultraviolet LED chip is used in the white conversion material. (3) Ca2BO3Cl: Ce 3 , the of Eu 2 the Ce 3 occupied Ca 2 two different Sites of produce broadband Blu-ray emission, Eu 2 generation yellow emission, Ce 3 and resonance energy transfer between Eu 2 by regulation of Ce 3 and the of Eu 2 relative concentration can be obtained the the single matrix white phosphor hope to become a near-ultraviolet LED chip with white light conversion material.
