This study presents a facile method for gram-scale synthesis of Mn-doped CsPbBr3 perovskite phosphors at room temperature, demonstrating dual-color emission with enhanced red emission. Additionally, two types of WLEDs were demonstrated with different chromatic performances, indicating potential applications in WLED devices.
Broadband emission Mn2+ doped lead halide perovskites are deemed as promising phosphor materials for solid state white light-emitting-diodes (WLEDs). Herein, we report a facile gram-scale synthesis of Mn-doped CsPb(Br/Cl)(3) phosphors by doping MnCl2 into CsPbBr3 perovskite nanocrystals at room temperature. The obtained phosphors present dual-color emission with blue emission at 463 nm and red emission at 602 nm. Increasing MnCl2 doping amount can enhance the red emission while more 3-Aminopropyltrimethoxysilane (APTMS) ligands can repress Mn related impurity and provide high stability. Further, two kinds of WLEDs (monocomponnet and two-component) are demonstrated. The monocomponent WLED exhibits warm white light under various driving currents (30 mA-150 mA), and the two-component WLED shows good chromatic performance close to ideal white light (0.33, 0.33), demonstrating their potential applications in WLED devices.
