摘要: We demonstrate highly efficient electroluminescence from silicon nanocrystals (SiNCs). In an optimized nanocrystal-organic light-emitting device, peak external quantum efficiencies of up to 8.6% can be realized with emission originating solely the SiNCs. The high reported here for first time that appropriate choice device architecture it is possible achieve indirect band gap semiconductor.
