Abstract

Quantum cutting downconversion involving the emission of two near-infrared photons for each blue photon absorbed is realized in transparent glass ceramics with embedded Pr 3 + Yb 3 + : β - Y F 3 nanocrystals. On excitation of Pr 3 + ions with a visible photon at 482 nm , Yb 3 + ions emit two near-infrared photons at 976 nm through an efficient cooperative energy transfer from Pr 3 + to Yb 3 + , with optimal quantum efficiency close to 200%. The development of the near-infrared quantum cutting transparent glass ceramic could open a route to enhance the energy efficiency of the silicon solar cell by converting one blue solar photon to two near-infrared ones.
