Although much effort has been focused on thermally enhanced upconversion (UC) luminescence, it remains a challenge to maintain or even enhance the UC luminescence of NaLnF 4 -based phosphors (Ln = Y, Gd, Lu) using a surface-independent strategy. In this work, we demonstrate that the effect of temper...
