Published: 19 Dec 2018

Quantum dots (QDs) can be defined as nanoscale semiconducting materials whose optical properties strongly differ according to its physical size due to quantum mechanical effects. QDs are able to absorb and emit photons within a narrow spectral range according to the particle size. Suspended in liquid media, QDs enable coating of the material through a variety of low-cost techniques, such as spin coating, spray, and dip coating among many other large-surface coating procedures. The distinctive features of QDs are attributed to its ability to tune light emission to a specific wavelength as well as its ability to use a single semiconducting material to emit different wavelengths by using particles of different sizes. Such distinct properties of QD enable generation of a white light output from red and green light coupled with a blue light-emitting diode (LED) light source. This leads to improvement in color gamut compared to yellow Cerium-doped Yttrium aluminum garnet (Ce:YAG) phosphors. Additionally, energy efficiency is enhanced as QDs re-emit most of the incoming light energy. QDs find significant use in photovoltaics and medical devices applications. However, commercial use is certainly focused on displays. Complementary technologies such as 3D printing and 4K and 8K ultra-high-definition (UHD) displays are enabling QDs to enhance consumer visual experience. Recent innovations in QDs are focused on addressing environmental concerns related to the presence or absence of cadmium or other heavy metals. Cadmium-free QDs exhibit higher growth rate due to their positive impact on products that are likely to be subjected to safety and environmental regulations.
