Abstract

ZnS nanocrystals are synthesized in polymer matrices. Absorption spectrum and small-angle X-ray scattering studies show that the size of the ZnS nanoparticles is 3.0 nm. Electron diffraction results show that the ZnS nanocrystals have hexagonal structure. A ZnS nanoparticle/polymer composite as an emitter is used to fabricate a single layer structure electroluminescent device with a low turn-on voltage (≤ 4 V) and blue electroluminescence is observed at room temperature.
