LUMINESCENT MATERIALS DOPED WITH METAL NANO PARTICLES AND PREPARATION METHODS THEREFOR

摘要

The invention belongs to the field of luminescent materials. Disclosed are luminescent materials doped with metal nano particles and preparation methods therefor. The luminescent materials doped with metal nano particles are represented by the chemical formula: A5-x(PO4)2SiO4:xRE@My, wherein @ is for coating, M is inner core, M is one metal nano particle selected from Ag, Au, Pt, Pd and Cu; RE is one or two ions selected from Eu, Gd, Tb, Tm, Sm, Ce, Dy and Mn; A is one or two elements selected from Ca, Sr, Ba, Mg, Li, Na and K; x is stoichiometric coefficient, 0
