Abstract Lanthanide-doped nanocrystals are promising for photon frequency upconversion with substantial spectrum tunability.However, the utilization of the Compression Socks upconversion process has been constrained by low luminescence efficiency, which may further attenuate at elevated temperatures due to thermal quenching.Herein, we report a vers
