Abstract To realize efficient and broadband near infrared (NIR) light in both NIR‐I NIR‐II regions, Gd 3 Mg 0.5 Al 1.5 Ga 2.5 Ge O 12 (GMAGG): Cr 3+ , Yb Ni 2+ phosphors are prepared this study. The effects of ‐Yb co‐doping ‐Ni tri‐doping on the luminescence properties investigated. GMAGG: exhibits high internal quantum efficiency (IQE) 96.4%, near‐zero thermal quenching (96.5%@423 K) 650–1100 nm. By constructing energy transfer from to emission range is further extended 650–1700 nm with a IQE 28% good stability (66%@423 K). NIR LEDs 0.04Cr 0.008Yb 0.04Ni exhibit 57.5 8.1 mW at an input current 100 mA, respectively. results show that promising phosphor for sources.
