Radio-, photo- and thermoluminescence were measured for two sets of PbWO₄ single crystal samples doubly doped with Mo and Nb⁵⁺/Ta⁵⁺ ions. Pentavalent ion codoping of PbWO₄ enhances the radioluminescence intensity to the level exceeding that of BGO scintillator. However, it introduces a new trapping level, which is reflected by the intense thermoluminescence-glow-curve peak around 100K.
