In article number 2100060, Wenge Xiao, Guojun Zheng, Jianrong Qiu, and co‐workers prepared far‐red‐emitting composite ceramics with near‐unity internal quantum efficiency and zero‐thermal quenching via pressureless glass crystallization, where the inside light scattering is finely tuned by controlling grain growth and the undesired concentration quenching is alleviated to achieve strong light absorption. Furthermore, a high‐power laser‐driven far‐red lighting source with high luminescence saturation is demonstrated.
