Research Abstract |
In this work, we demonstrated synthesis of deep-blue emissive colloidal quantum CdS@ZnS dot (QDs) with chemical-composition gradient through one-step modified-hot injection method. The aqueous solutions containing these QDs showed side-dependent deep-blue fluorescence centered at 430-480 nm with more than 80% of quantum yield. We further demonstrated their monolayer fabrication deposited directly on PVC/PEDOT-PSS integrated layer with no significant degradation. Because the monolayer also showed brilliant deep-blue emission under UV light irradiation, we believe that newly-demonstrated flux technique will be one of the strong candidate materials for next-generation light emitting device materials.
