Abstrak

In this study, it was demonstrated that Zn3Ta2O8 crystals containing zinc oxide with high vapor pressure can grow in melt by the shielded arc melting method. The radiation response characteristics of the crystals were evaluated. The grown crystals showed an emission peak at 410 nm, ascribed to self-trapped excitation, Ta4+–O2−. The full width at half maximum of the X-ray rocking curve was 655 arcsec. The light output under 662 keV gamma-ray irradiation of Zn3Ta2O8 was approximately 4,700 photons/MeV. The decay time was 17.3 μs? Thus, the shielded arc melting method was shown to be a quick and economic growth technique for the survey of new scintillator materials containing high-vapor-pressure starting components.
