WebElectron-phonon coupling was believed to govern the carrier transport in halide perovskites and related phases. Here we demonstrate that electron-electron interaction enhanced by Cs-involved electron redistribution plays a direct and prominent role WebThe synthesis of α-CsPbI 3 perovskite quantum dots (QDs) with pure red emission around 630 nm is in high demand for display backlight application. However, the phase transition of α-CsPbI 3 to yellow non-emitting δ-CsPbI 3 has been proven to be a great challenge for the classic colloidal synthesis route for perovskite QDs in octadecene (ODE).
