Highly luminescent nanoscale quasi-2D layered lead bromide perovskites with tunable emissions

Herein, we report a new color tuning approach for highly luminescent nanoscale lead(II) bromide perovskites with a quasi-2D layered structure. By synthetically manipulating the quasi-2D layered structure, different quantum size confinement effects can be realized to enable a precise color tuning of emissions ranging from deep blue to bright green.
