Abstract
Using eye catching demos and the size-dependent properties of quantum dots (QDs) we can appeal to a broad range of students, from high school and general chemistry students to those in more advanced chemistry and physics courses. This experiment is easily tailored to meet the requirements of the instructor and equipment availability. Visually observed fluorescent colors of QDs in conjunction with spectroscopic data show students the additive emission of QD mixtures. Although some mixtures appear to emit white light, their fluorescence peaks remain spectroscopically resolved; this is not possible using organic dyes. More advanced topics on inorganic synthesis and energy transfer can be discussed for students of higher levels.
