摘要: Yb3+and Er3+ co-doped BaF2 phosphors were prepared by high temperature solid reaction method. Effects of mol content ratios Yb3+ ion to Er3+ion (CYb3+∶CEr3+) and charge compensation agent Na2SiF6 contents on the up-conversion luminescence samples studied. The XRD PL carried out investigate phases luminescence. Three emissions observed with peaks at 460nm, 548nm 660nm respectively. intensity increases firstly, then decreases increasing CYb3+∶CEr3+ optimal ratio was found be 12:2 fixed 2mol%. emission enhanced introducing as agents its
