Abstract
Official abstract text for this publication.
Borate luminescent materials, preparation methods and uses thereof are provided. The luminescent material is a blend of metal M nanoparticles and (In 1-x Re x )BO 3 , wherein Re is one or two selected from Tm, Tb, Eu, Sm, Gd, Dy and Ce, M is one or two selected from metal nano particles of Au, Ag, Pt or Pd, 0<x≦0.5, 0<z≦1×10 −2 . Compared to the luminescent materials in the prior art, the said luminescent materials have higher luminous intensity and luminous efficiency, which can be used in field emission displays or light source.
