Quantum cutting downconversion involving the emission of two near-infrared photons for each blue photon absorbed is realized in transparent glass ceramics with embedded ${\mathrm{Pr}}^{3+}∕{\mathrm{Yb}}^{3+}$ : $\beta \text{-}\mathrm{Y}{\mathrm{F}}_3$ nanocrystals. On excitation of ${\mathrm{Pr}}^{3+}$ ions with a visible photon at $482\mathrm{nm}$ , ${\mathrm{Yb}}^{3+}$ ions emit two near-infrared photons at $976\mathrm{nm}$ through an efficient cooperative energy transfer from ${\mathrm{Pr}}^{3+}$ to ${\mathrm{Yb}}^{3+}$ , 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.
