Abstract

Transparent Nd3+-doped Ba(Zr,Mg,Ta)O3 ceramics with disordered-type crystals were fabricated by adjusting the Ba(Zr,Mg,Ta)O3 composition in order to substitute Nd dopants at different crystal sites. The XRD and XRFS analyses show that the substitution site of Nd ions changed as expected. In samples excited by a 805nm laser diode, the shape of the fluorescence spectrum in the 4F3/2→4I11/2 transition depends on the Ba(Zr,Mg,Ta)O3 composition, and a maximum full width half maximum of 30.5nm was obtained. In addition, the fluorescence efficiency also improved by adjusting the Ba(Zr,Mg,Ta)O3 composition.
