A higher signal‐to‐noise ratio in the application of bio‐imaging requires the development of a persistent phosphor, featuring multi‐ and broad emission bands in the NIR biological window. In article number 1701161 by Yang Li, Yihua Hu and co‐workers, the coordination geometry‐dependent multi‐band emission is discovered in chromium‐doped aluminates. Deep‐tissue ex vivo imaging and in vivo imaging both demonstrate the superiority of the multi‐band‐emissive material in high‐quality bio‐imaging.
