ZnBr2-Assisted Br-Rich Regulation of Blue-Emitting CsPbBr3 Nanoplatelets Synthesized at Low Temperature.
All-inorganic CsPbBr3 nanoplatelets (NPLs) have attracted considerable interest for light-emitting, wavelength-conversion, and flexible photonic applications owing to their high color purity, tunable bandgap, and excellent luminescence performance. However, their large specific surface area makes them highly susceptibl...
