摘要：

Photoluminescence (PL) in PbWO4 single crystals doped with Pr3+, Sm3+, and Er3+ ion, which were grown by the Czochralski method, was studied. By investigating the PL for incident radiation with wavelength of 325 nm (He-Cd Laser), the energy levels of the PL centers were found: The PL levels in the Pr doped single crystal are P-3(o) and D-1(2), that in the Sm-doped one is (4)G(5/2), and those in the Er doped one are H-2(11/2), S-4(3/2), and F-4(9/2). In conclusion, the characteristics of these single crystals are governed solely by those of the rare-earth dopants, not by the lead tungstate. (C) 2002 American Institute of Physics.
