Mn2+ doping in metal halide perovskites enables host-to-dopant energy transfer, creating new emission pathways for optoelectronic applications. However, achieving high-efficiency luminescence 2D systems remains challenging. We synthesized Mn2+-doped PEA2CdCl4 via the hydrothermal method, characterizing its properties through PL spectroscopy, quantum yield measurements, and DFT calculations. Flexible films were fabricated using PDMS PMMA matrices. The 15% crystal showed orange–red with 90.85% PLQY, attributed to efficient host-to-Mn2+ transfer 4T1→6A1 transition. Prototype LEDs exhibited stable emission, while demonstrated flexibility excellent X-ray imaging capability. This work demonstrates as an effective strategy enhance perovskites, potential applications flexible optoelectronics scintillators.
