Abstract

Under synchrotron vacuum ultraviolet excitation, three different hafnates (BaHf(PO4)2, BaHf(BO3)2 and BaHfSi3O9) show self-activated luminescence with peaks ranging from 275–335 nm, which is attributed to the charge-transfer luminescence from the hafnate (HfO68−) group. Upon doping Eu2+ into BaHfSi3O9, host sensitization of Eu2+ emission via hafnate intrinsic emission is demonstrated.
