High color purity ZnSe/ZnS core/shell quantum dot based blue light emitting diodes with an inverted device structure

Wenyu Ji, Pengtao Jing, and Wei Xu et al.

Deep-blue, high color purity electroluminescence (EL) is demonstrated in an inverted light-emitting device using nontoxic ZnSe/ZnS core/shell quantum dots (QDs) as the emitter. The device exhibits moderate turn-on voltage (4.0 V) and color-saturated deep blue emission with a narrow full width at h ... [Appl. Phys. Lett. 103, 053106 (2013)] published Tue Jul 30, 2013.
