Abstract
The authors report, for the first time, high colour purity short perio d superlattice (SPSL) II-VI blue light emitting diodes (LEDs) grown by molecular beam epitaxy. The room temperature electroluminescence spec trum showed pure blue emission at 460nm with a 13nm full width at half maximum (FWHM). The external quantum efficiency is similar to 0.1%. O perating at 14 Acm(-2), the half-intensity lifetime was >13h at room t emperature.
