Visible quantum cutting in Pr3+:PbWO4 crystal through energy transfer between the host and Pr3+ ions

Quantum cutting observed in Pr3+:PbWO4 crystal consists of the 1S0 → 1D2 and 1D2 → 3H4 transitions. Energy transfers between the host and Pr3+ ions can convert the ultraviolet emission from 1S0 → 1D2 into a visible emission. This work provides a potential approach for the development of high efficient visible quantum cutting phosphors and scintillators.
