Abstract

Multi-shell Cd-free nanocrystals were designed such that (1) the outer-most shell was free of reactive sulfide to prevent corrosion (2) the position of the band-edge emission remained unchanged during multi-shell coating. The photoluminescence and photostability were markedly enhanced and allowed the fabrication of light-emitting diode devices with high color-rendering abilities and high photostability.
