Development of perovskite-based light emitting diodes with improved stability 6.0

The all-inorganic colloidal CsPbX3, (X = Cl, Br, I) nanocrystals are being studied broadly as a new candidate of optoelectronic material because of its tunable wavelength and high photoluminescence quantum yield (PL QY). Nevertheless, the instability of the nanocrystals due to the delocalisation of...
