Pressure-induced emission (PIE) in halide perovskites toward promising applications in scintillators and solid-state lighting

High-pressure chemistry has provided a huge boost to the development of scientific community. Pressure-induced emission (PIE) in halide perovskites is gradually showing its unique charm in both pressure sensing and optoelectronic device applications. Moreover, the PIE retention of halide perovskites under ambient conditions is of great commercial value. Herein, we mainly focus on the potential applications of PIE and PIE retention in metal halide perovskites for scintillators and solid-state lighting. Based on the performance requirements of scintillator and single-component white light-emitting diodes (WLEDs), the significance of PIE and PIE retention is critically clarified, aiming to design and synthesize materials used for high-performance optoelectronic devices. This perspective not only demonstrates promising applications of PIE in the fields of scintillators and WLEDs, but also provides potential applications in display imaging and anti-counterfeiting of PIE materials. Furthermore, solving the scientific disputes that exist under ambient conditions is also simply discussed as an outlook by introducing high-pressure dimension to produce PIE. Pressure-induced emission (PIE), which refers to a novel phenomenon whereby a nonluminescent material exhibits emission upon compression, offers a great step forward to light up the better future. PIE materials not only show promising applications in the fields of scintillators and solid-state lighting, but also provide potential applications in display imaging and anti-counterfeiting.image
