Effects of Zr4+ codoping on the Lu0.8Sc0.2BO3:Ce scintillation materials

► No positive contribution of the Zr4+ ions on the scintillation efficiency was found. ► New optical absorption band was in the region from 200 to 225 nm. ► Continuously accelerated decay time indicated that Zr4+ codoping induced new point defects. ► The induced hole trap located at 1.91 eV below the conduction band.
