Optical Properties of Fluorescent Mixtures: Comparing Quantum Dots to Organic Dyes.

The article demonstrates the optical properties of mixtures of quantum dots (QDs) and compares the results to fluorescent organic dyes. It is noted that the solutions of mixtures of QDs of different sizes produce colors that are the sum of the fluorescence wavelenghts of the individual QD components. To further understand why mixtures of quantum dots and organic dyes have different appearances, optical properties of both quantom dots and organic dyes are measured using absorption and fluorescence emission spectroscopy.
