Solvatochromic fluorescent carbon dots as optic noses for sensing volatile organic compounds†
Abstract
Amphiphilic carbon dots (CDs) with strong solvatochromism were synthesized via solvothermal method. The as-synthesized CDs demonstrate outstanding photoluminescence properties consisting of a high fluorescence quantum yield along with tunable photoluminescence (from blue to orange emission), which make them an ideal candidate for the detection of volatile organic compounds.
