Advanced Science, EarlyView.Highly efficient and thermally stable NIR photonic materials with emission over 830 nm are designed. A cation site substitution strategy is proposed to regulate the Stokes shift of the NIR emitters. The phosphors exhibit a full visible‐spectrum conversion ability from 400 to 800 nm, showing great promise for NIR spectroscopy applications in solar ...
