A high-performance metal halide perovskite-based laser-driven display

“…S1, ESI †). 33,34 It is inferred that the brightness difference of the MHP solids is inextricably linked to their surface structure instead of the bulk structure. In Fig.…”

“…This confirms that there is no interaction between the hydrocarbon chains and the defects. 33,34 Interestingly, the absorption peaks of MHP-C 8 at 3486 cm À1 gradually disappear and reappear in the heating-cooling cycles (Fig. 3e), implying the metastable fracture and intact surface coordination bonds between R-NH 2 and V Br À26, 27 The metastable fracture of the surface coordination bonds between R-NH 2 and V Br À is ascribed to the strong vibration at high temperature, leading to the disappearance of the absorption peak at 3486 cm À1 .…”
