This dataset is derived from a study on the synthesis and luminescence performance regulation of rare earth near-infrared (NIR) luminescent nanocrystals, and contains near-infrared luminescence spectra and quantum yield data of rare earth nanocrystals. The synthesis of high-efficiency rare earth NIR luminescent nanocrystals is of great significance for improving the signal-to-noise ratio (SNR) and sensitivity of biological imaging. This work investigated the quantum yields of nanocrystals doped with various rare earth ions, and observed that LiLuF4:Nd@LiLuF4 nanocrystals exhibited a high NIR luminescence quantum yield of up to 32%. The data were collected using a fluorescence spectrometer (Edinburgh FLS-980) from November 1, 2017 to May 1, 2022 at Peking University. This dataset corresponds to the high-efficiency near-infrared luminescence of rare earth nanomaterials specified in the relevant technical indicators, with a total data volume of approximately 1 MB.
