Influence of trivalent ions codoping on the Mo:PbWO4 luminescence properties

Abstract Trivalent ions codoping Mo:PWO boules were grown along the c -axis using the Czochralski technique. Trivalent ions codoping improved the fast components of luminescence for Mo:PWO due to suppression/compensation of hole-trapping centers. Correspondingly, trivalent ions codoping increased the fast components of the light yield. The La 3+ and Gd 3+ concentration in the crystal gradually decreased along the growth direction because they increased the melting point. The Y 3+ concentration increased along this direction due to the different influence on the melting point. Compared with La:Mo:PWO, Y:Mo:PWO shows a more uniform transmittance along the growth direction.
