Dallas, TX -- (SBWIRE) -- 06/25/2014 -- Quantum dots (QDs) are semiconductor nano-crystals that possess unique optical properties including broad-range excitation, size-tunable narrow emission spectra, and high photo stability, giving them considerable value in various applications. The size and composition of QDs can be varied to obtain the desired emission properties and make them amenable to simultaneous detection of multiple targets. Furthermore, numerous ‘surface functionalizations’ can be used to adapt QDs to the needed application.
From the opportunity pockets stand point, it has been observed that QD LED and QDD are expected to get fully commercialized by the end of 2015-16, as there is a strong R&D going on in this field and in solid-state lighting. QD-based lighting is expected to be the best replacement to the currently available CFL and LED lighting, as this provides better efficiency and high power intensity. The research in this field is at the pilot stage and is anticipated to fully commercialize in the recent future. Quantum dots have a peculiar property to absorb maximum light luminance; hence, they can be used as a technology to provide better efficiency to solar panels. Therefore, QD solar cells and panels are expected to be the biggest revolution in the field of solar energy; and they are anticipated to be fully commercialized by 2016-17.

Quantum Dots (QD) comprise the most advanced area of "semiconductor nanoparticles", wherein a host of massive research activities are currently being undertaken. QDs are semiconductor nano particles, and as the name suggests, come in sizes ranging from 2 nm to 10 nm. Due to their miniature property; they are highly versatile and flexible. The uniqueness of QD material lies in the fact that its power intensity depends on the input source and size of QD. There are several ways to confine excitons in semiconductors, resulting in different methods to produce Quantum Dots Market. In general, quantum wires, walls, and the dots are grown by advanced epitaxial techniques in nano crystals produced by chemical methods or by ion implantation, or in nano devices created from state-of-the-art lithographic techniques.
“Quantum Display” or “QD Displays (QDD)” is one of the biggest developments to have occurred recently. A QD display is a type of display technology providing better feature as compared to Cathode Ray Tubes (CRT) and Liquid Crystal Displays (LCD).This technology is similar to organic Light Emitting Diode (OLED), which provides more efficient displays. It provides 50 to 100 times better brightness in comparison to CRT display and LCD. LCD does not produce a pure green, red, and blue color. On the other hand, Quantum Dot Display produces pure colors.

Quantum Dots have fluorescence effect, which occurs when the excited electron moves from the conduction band to its valence band, emitting a photon with a longer wavelength than the one absorbed (electron–hole recombination process). The energy difference between the absorption and emission spectra is known as the “Stokes shift”. Generally, the smaller the crystal size, the larger is the band gap. Therefore, the electron will require more energy to become excited, and in turn, will emit light with a higher energy while returning to a lower energy state. The color and emission wavelength of a QD are determined by its size and composition. QDs can emit light at wavelengths ranging from the ultraviolet (UV) to the infrared (IR).
Another dimension of QuantumDots would be to undergo the phenomenon known as “Forster Resonance Energy Transfer (FRET)”, which is of popular utility in the development of biosensors and detection assays. FRET is the nonradioactive transfer of energy from a donor molecule to an acceptor molecule through near-field dipole–dipole interaction. In addition, to overlap between the emission spectrum of the donor and the absorbance range of the acceptor, a typical distance of 2–8 nm (known as the Forster distance) between the donor and acceptor is needed; thus, resulting in the energy transfer. The “Forster distance” is defined as the distance between the donor and acceptor, at which the energy transfer efficiency is 50%. The advantages of using QDs as energy donors in FRET-based assays include their strong emission and multiplexing ability as well as the option to choose the QDs with the emission wavelength most suited for the available acceptor.
The QD market is expected to grow from $108.41 million that it accounts for, currently, in 2013 to $3,414.54 million in 2020, at a CAGR of 71.13% from 2014 to 2020. Optoelectronics application is expected to be the major market share holder with an expected revenue generation of $2,458.47 million in 2020.
