Solid solution crystals of Lu1−xScxBO3:Ce3+ (x = 0.2, 0.3, 0.5, 0.7) were grown by Czochralski method. These crystals have high optical transmittance within wavelength concerned, except for an absorption shoulder in Lu0.8Sc0.2BO3:1at%Ce3+ crystal from 360 to 530 nm. With the increase of Sc/Lu ratio, the excitation and emission spectra have redshift due to change of Ce3+ crystalline environment and the lifetime gradually increases due to the increase of emission wavelength. Efficient energy transfer from the self-trapped excitons to Ce3+ ions was observed. Lu0.8Sc0.2BO3:1at%Ce3+ crystal, due to high density, short decay time, high scintillation efficiency and non-hygroscopic property, could be a promising scintillator.
