Colloidal nanoplatelets (NPLs) are a kind of two-dimensional nano-material with an atomically flat surface, leading to an ultra-narrow emission linewidth of 8 & x007E;12 nm. In this article, we fabricated green light-emitting diodes (LEDs) based on CdSe/CdS core/crown NPLs. This device exhibited an electroluminescence (EL) at 521 nm with a full-width at half maximum (FWHM) of 15 nm and a maximum luminance of 4684 cd/m(2). Such narrow EL FWHM indicates that the core/crown NPLs can achieve an ultrapure green LED with 124.7 & x0025; of National Televison System Committee (NTSC), realizing a high color saturation and wide color gamut display.
