Abstract

Yb3+and Er3+co-doped BaF2phosphors were prepared by high temperature solid reaction method. Effects of mol content ratios of Yb3+ion to Er3+ion (CYb3+∶CEr3+) and charge compensation agent Na2SiF6 contents on the up-conversion luminescence of the samples were studied. The XRD and PL were carried out to investigate the phases and the up-conversion luminescence. Three up-conversion emissions were observed with peaks at 460nm, 548nm and 660nm respectively. The up-conversion luminescence intensity increases firstly, and then decreases with increasing CYb3+∶CEr3+ and the optimal ratio was found to be at 12:2 with fixed Er3+contents 2mol%. The up-conversion emission intensity was enhanced by introducing Na2SiF6 as the charge compensation agents and its optimal content was found to be 2mol%.
