High‐radiance near‐infrared (NIR) phosphor‐converted light‐emitting diodes (pc‐LEDs) are demanded for wearable biosensing devices and the properties of these pc‐LEDs are highly dependent on the performance of the NIR phosphor. An ultraviolet–visible and NIR‐responded broadband NIR NaScGe2O6:Cr3+ pho...
