The mechanism of X-ray excited luminescence in BaHfO3 doped with Eu3+, Y3+ or Eu3+, La3+

Anna Dobrowolska , Eugeniusz Zych

Abstract

Luminescent properties of BaHfO3:Eu codoped with Y3+ and La3+ were investigated. It was found that the codopants influence the location of Eu3+ in the host lattice. Y3+ directs Eu3+ into Ba2+ and La3+ channels Eu3+ into Hf4+ site. The mechanism of the process is discussed. Both, Eu'(Hf) and E(u) over dot(Ba) show photoluminescence but only the former one exhibits X-ray excited luminescence. This phenomenon is explained based on the electronic structure of BaHfO3 host.
