摘要：

A strategy of achieving efficient orange emissive carbon nanodots (CNDs) with large sized conjugated sp(2)-domain is achieved in a solvothermal synthetic route using dimethylformamide as solvent, which is the basis of orange bandgap emission; enhanced orange emission with photoluminescent quantum yield of 46% is realized through surface charges engineering by surface metal-cation-functionalization.
