摘要
Broadband near-infrared(NIR) light sources demonstrate great potential in quantitative food analysis, material identification,invasive brain imaging diagnosis, and real-time health monitoring fields, etc. [1–3]. Compared with competing technologies based on quantum dots and organic crystals, NIR-emitting phosphor converted light-emitting diodes(pc-LEDs) favor high spectral modulation and physicochemical stability [4].
