摘要：

Visible quantum cutting has been observed in Pr3+-doped PbWO4 crystal under ultraviolet excitation. Quantum cutting in this crystal consists of the S-1(0) -> D-1(2) (around 325 nm) and D-1(2) -> H-3(4) transitions (around 604 nm). Energy transfers between the host and Pr3+ ions can convert the ultraviolet emission from the S-1(0) -> D-1(2) transition into a visible emission from the P-3(J) (J = 0, 1) and D-1(2) multiplets in the range of 490-650 nm. This work provides a potential approach for the development of high efficient visible quantum cutting phosphors and scintillators. (c) 2006 Elsevier B.V. All rights reserved.
