초록
Pr-doped CaHfO3 bulk crystals were synthesized by the floating zone method, and the luminescence properties wereinvestigated. We confirmed that all the samples have a single phase of CaHO3 by XRD measurement. The undoped sampleindicate a broad emission around 440 nm and fast decay time constant due to the host while the Pr-doped samples show sharppeaks and slow decay time constants due to the 4f-4f transitions of Pr3+. By Pr-doping, the afterglow level became worse thanthat of the undoped one while the dense Pr-doping can suppress the afterglow.
