Metal-halide perovskites (MHPs) have attracted tremendous attention because of their excellent performance in photovoltaic devices, such as solar cells. However, because of the crucial relationship between emission intensity and performance, pressure-quenching of optical emission greatly restrict the potential application of MHPs. Here, we reported the unique pressure-induced emission enhancement (PIEE) of CsPbxMn1-xCl3 NCs. Different from other PIEE phenomena, the PIEE of CsPbxMn1-xCl3 NCs was caused by the enhancement of energy release from T-4(1) to (6)A(1) of the Mn, attributed to the pressure-induced isostructural phase transition. Meanwhile, the photoluminescence (PL) can exist until almost 20 GPa, suggesting that CsPbxMn1-xCl3 NCs exhibited better environmental suitability and worked under high pressure. Our studies explored the relationship between bandgap microstructure and optical properties of CsPbxMn1-xCl3 NCs at high pressure and also gave insights into the optimization of photovoltaic performance, which promoting the design of functional MHPs.
