Make quantum dots: Combine 13mg of cadmium oxide, 0.6mL of oleic acid and 10mL of 1-octadecene. Heat the mixture until the cadmium oxide completely dissolves to form cadmium oleate. After the cadmium oxide dissolves keep heating until the mixture hits 225 degrees celsius. Inject 1mL of the trioctylphosphine selenide solution from before and shake.

Buy cadmium selenide quantum dots or CdSe quantum dots from NN-Labs for their monodisperse size distribution and flexible processability. The CdSe core quantum dots can be excited over a broad range of wavelengths and emit with a narrow peak, yielding color-pure emission that spans nearly the entire visible spectrum. The CdSe core quantum dots are a lower cost alternative great for ...

Quantum dots may be able to increase the efficiency and reduce the cost of today's typical silicon photovoltaic cells. According to an experimental report from 2004, quantum dots of lead selenide can produce more than one exciton from one high energy photon via the process of carrier multiplication or multiple exciton generation (MEG). This ...
