Quantum dots are semiconductor particles with diameters between 1-100 nanometers. These particles are larger than small molecules, but smaller than bulk semiconductors (which can still micrometer-sized). The smallest range of quantum dot sizes includes “magic sized” nanoclusters, which have known chemical formulas such as Cd13Se13 and Zn34S34. Quantum dots act as tunable light absorbers and emitters – by changing the size of a quantum dot, it can be made to emit colors of light ranging from red to blue.
Example elemental compositions of quantum dots include CdS, CdSe, or InP. These materials can be tuned to luminesce and absorb light across the visible spectrum, which has made them useful in consumer electronics like televisions. However, some of these materials are relatively toxic or are uncommon in the Earth’s crust.
My research focuses on understanding the chemistry of magic sized quantum dots. Topics include:
