| 英文摘要 | Zn and RE (RE= La, Yb, Y) ions co-doped PbWO(4) (PWO) single crystal grown by the Czochralski technique are characterized by x-ray diffraction (XRD), optical transmission spectra, and photoluminescence (PL). The doping of Zn ions shows distinct effects on the properties of PWO: RE crystals. At low concentration of Zn ions (200 ppm), the luminescence intensity is quite weak for (Zn, La)-doped PWO, but is substantially strong for (Zn, Yb)-doped PWO. The blue luminescence intensity is significantly enhanced with the increasing Zn ions doping for PWO: Y. The trivalent ions codoping can increase the ratio of the blue luminescence contributing to the fast components of light yield. Yb ions can enhance efficiency of luminescence in PWO: Yb: Zn because they may act as a luminous sensitization agent which can be involved in the efficient energy transfer and storage of the radiative process. |
