Broadband Emission
In article number 2109618, Wenge Xiao, Ling‐Dong Sun, and co‐workers develop a visible–near‐infrared emitting phosphor based on the combination of the dual roles of Mn2+ in generating red and near‐infrared emission and the energy transfer from Ce3+ to Mn2+ in Lu2BaAl4SiO12 garnet. Their study demonstrates that Mn2+ with highly symmetric coordination can serve as an activator for...
The development of extra‐broadband emitting phosphors is challenging but meaningful work. So far, however, phosphors that can be effectively excited by GaN‐based blue light‐emitting diode (LED) chips and emit from visible (VIS) to near‐infrared (NIR) regions are still rare. Herein, this study designs an extra‐broadband VIS‐NIR emitting phosphor with emission band ranging from 460 nm to 880 nm (bandwidth...
