| Abstract Scope |
Near-infrared (NIR) phosphor-converted light-emitting diodes (pc-LEDs) have been explored as the next generation of NIR light sources for applications in food composition analysis, medical imaging, bio-sensing, and photomorphogenesis for plants. However, the development of NIR phosphors that simultaneously produce longer-wavelength broadband emissions and with high thermal stability continues to be a difficult challenge. Here we have designed and reported novel phosphate-based phosphor with thermally stable broadband NIR luminescence. We have also clarified their anti-thermal quenching mechanisms using a combination of first-principles analysis and experimental study. This work is expected to encourage further research into crystal structural control to create new and thermally stable phosphors with practical uses. |
