Achieving a Balance of Good Quantum Efficiency and Thermal Stability in the Y₂CaScAl₃GeO₁₂:Cr³⁺ Broadband Phosphor for Multiple NIR Spectroscopy Applications

Near-infrared phosphor-converted light emitting diodes (NIR pc-LEDs) are considered as desirable NIR light sources to satisfy current needs owing to their numerous remarkable features. Nevertheless, as an essential component, previously reported NIR phosphors with broadband emission often suffer from inferior efficiency or thermal stability, therefore restricting their use and promotion. Herein, a novel Cr
