Investigating rare earth doping in a halide perovskite using solid-state NMR

Thiago Rubio – @thi_53

Ytterbium-doped halide perovskites are known to display the quantum cutting effect: one high-energy photon is converted into two low-energy photons. Dry mechanosynthesis, a simple, yet powerful method, was used to make the chloride perovskites, and NMR spectroscopy was used to analyze the effects of the doping in the perovskite structure.
