Spin‐Flip Upconversion Luminescence and Tunable Downshifting Near‐Infrared Emissions via 4 <i>d</i> ‐4 <i>f</i> Interaction in Doped Halide Perovskite
f-electrons excitation at 980 nm. This finding establishes 4d-4f interaction as a strategy to simultaneously tune downshifting and UC pathways, opening a new opportunity to tailor optical and optoelectronic materials.
