Abstract Perovskite, as a novel luminescent material, is widely used in light-emitting diodes (LED). Among them, the inorganic non-lead perovskite Rb₂CuBr₃ has attracted significant attention in recent years due to its environmental friendliness and high stability. However, the intrinsic ultraviolet emission of Rb₂CuBr₃ limits its application. This work proposes a co-sintering method to prepare Mn-doped Rb₂CuBr₃, tuning its emission range to the visible light spectrum, and exploring the luminescent mechanism of the crystal through changes in the band gap value. At a doping concentration of 5%, the prepared Mn-doped Rb₂CuBr₃ phosphor-converted LED (pc-LED) achieves a high color rendering index (CRI) of 88.1, enabling precise control of the LED's emission color to meet the demands for lighting quality and energy efficiency in various fields. This provides a feasible method for the preparation of novel LEDs.
