中科院长春光机所白光LED课题组在继研制出蓝光LED转换成白光用新型稀土发光材料之后,开展了紫光LED转换成白光用新型稀土发光材料的研究工作,并成功研制出紫光LED转换成白光用新型稀土发光材料。新型稀土发光材料具有较宽的激发带,激发光谱范围在250~450nm,发光光谱覆盖可见
Following the development of a new type of rare earth luminescent material for converting blue light LED into white light, the white LED research group of Changchun Institute of Optics and Fine Mechanics of the Chinese Academy of Sciences conducted a research work on the conversion of violet LED into white light with a new type of rare earth luminescent material and successfully developed the violet LED into white light With a new type of rare earth luminescent materials. The new rare earth luminescent material has a wide excitation band, the excitation spectrum in the range of 250 ~ 450nm, the emission spectrum covered visible
