Highlights: • Three-photon near-infrared quantum cutting is obtained in β-NaYF{sub 4}:Er{sup 3+} NPs. • Quantum cutting efficiency as high as 242.59% is calculated from decay curves. • Plasmon-enhanced three-photon quantum cutting is achieved by Ag nanocubes. • The maximum quantum cutting enhancement factor reaches 2.86. - Abstract: The near-infrared (NIR) quantum cutting (QC) nanoparticles (NPs) β-NaYF{sub 4}:Er{sup 3+} are prepared by coprecipitation method. Three-photon NIR QC luminescence at 1520 nm ({sup 4}I{sub 13/2} → {sup 4}I{sub 15/2}) is obtained under the excitation of 519 nm ({sup 4}I{sub 15/2} → {sup 2}H{sub 11/2}). The corresponding QC efficiency η{sub QC} calculated from the luminescence decay curves reaches as 242.59%. Furthermore, three-photon NIR QC luminescence is enhanced by the localized surface plasmon resonance of Ag nanocubes (NCs). The influence of Ag NCs concentration on three-photon QC luminescence is investigated, and the results show that the optimal concentration of Ag NCs is 0.10% with the enhancement factor reached a maximum as 2.86. Our study may have potential application as a QC layer to improve the photovoltaic conversion efficiency of germanium (Ge) solar cells.
