Quantum dots are nanocrystals made from semiconductor materials which are unique material slowly penetrating different fields in optoelectronic and photovoltaics. The global quantum dots market is expected to increase from just around $235m in 2013 to around $2.85bn by 2018. Quantum dots have an inverse relation with respect to their size and band gap and this result in their key optical property of change in color. As the dot size decreases, the color of light emitted changes from red to blue. 更多
