Pressure-induced robust emission in a zero-dimensional hybrid metal halide (C9NH20)6Pb3Br12
Fig. 1.
Fig. 2. Bandgap evolution of (bmpy)6[Pb3Br12] under high pressure. (a) UV-vis absorption spectra at high pressures. (b) Bandgap as a function of pressure. The insets show optical micrographs at selected pressures. (c) Bandgap evolution of (bmpy)6[Pb3Br12] compared with other hybrid metal halides, where the data are collected from the literature.

Fig. 4. (a) PL emerging and quenching pressures of (bmpy)6[Pb3Br12] in comparison with those of other 0D and 1D metal halides. (b) Stokes shift and phonon energy as functions of pressure. (c) Schematic of pressure-induced emission from excitons. GS and ES indicate the ground state and excited state, respectively.
