Abstract
⺠Pr3+, Mn2+ co-doped K2YZr(PO4)3 phosphor is a novel type of practical visible quantum cutting phosphor in promising application. ⺠The optimal quantum efficiency (QE) of this co-doped system K2YZr(PO4)3: Pr3+, Mn2+ reached to 126.3%. ⺠The Mn2+6A1g â 4Eg-4A1g transition was found to coincide well with the 1S0 â 1I6 transition of Pr3+. ⺠The energy transfer from Pr3+ to Mn2+ was also observed, converting the first photon from the PCE of Pr3+ into the red emission of Mn2+, and the QC process occurred in this Pr3+, Mn2+ co-doped K2YZr(PO4)3 phosphor.
