Near-Infrared Quantum Cutting Material Er3+/Yb3+ Doped La2O2S with an External Quantum Yield Higher than 100%

Résumé

Near-infrared quantum cutting is widely studied for its potential application in photovoltaic solar cells. By using a fluorometer equipped with an integrating sphere, we measured the external quantum yield of near-infrared quantum cutting in Er3+/Yb3+ doped La2O2S. It is found that by optimizing the synthesis process and the dopant concentration, the external quantum yield higher than 100% can be achieved. Additionally, by comprehensively considering the emission efficiency of the dopants as well as the energy transfer efficiency between them, the estimated quantum yield could be in good accordance with the measured one.
