Abstract

Upconversion photoluminescence (PL) of ErYb3+-doped BaTiO3(BTO) with perovskite ABO3structure is studied in terms of ErYb3+substitutions for Ba (A-) and Ti (B-site) with different ErYb3+doping concentrations. PL quenching with an increase ErYb3+doping concentration is investigated based on the structural change and energy transfer of cross-relaxation process in BTO: Er, i.e.2H11/2+4I15/2→4I9/2+4I13/2. Temperature dependence of the PL in BTO: Er is revealed, which is associated with phase transitions of BTO host. The results imply that the emission from substituted ErYb3+ions may be used as a structural probe for the ferroelectric titanates.
