All That You Need to Know About the Quantum Dot Technology

Quantum dot technology is one of the latest innovations in the technological world, and it is a vital progress that can bring about several crucial developments.

Quantum dot can be termed as a portion of matter and the “excitons” can be confined into three spatial dimensions. These particles do have electronic properties, and they were discovered in the year 1980.


Quantum Dot Technology for Mobile Devices and Flat Screens

Thin-film panels’ production can be accomplished using Quantum Dot nanotechnology as well as through the contact printing. With the Dot Technology, the picture resolution is pretty high. QDs or Quantum Dots are part of liquid crystal display of nano-crystal semiconductor technology. LCD is a thin layer, which acts as an electro-active sheet deposited over non-planar flexible substrates.

Conservative LED molecules are pretty sensitive to the humidity and oxidation. These molecules have decent propensity to degrade. Inorganic and organic QD LEDs symbolize next-generation display technology, and they’ve got lots of advantages. You can see these advantages exploited in tablets, flat-panel TVs, digital cameras, and high end mobile phones.

Nano-crystal properties and performance are determined by the size and composition of quantum dots that are electroluminescent and photo luminescent as well.




Optical Properties

QDs do have some unusual properties, which mainly depends upon the energy levels and sizes. Quantum incarceration effect depends upon the QD coloration, and it is unswervingly related to the QDs energy levels.

The Quantum dots have exclusive physical properties that can be integrated easily into the OLED displays.

QDs comprise of better color, purity, and they are more flexible due to assimilation of non-aqueous and soluble aqueous solvents. This property offers printable flexible displays of various sizes. You can see large areas are covered on the displays of LEDs screens.

LED displays work based on QD with saturated colors having narrow bandwidth. The wavelength is tuned by changing the QD size, and the display can cover the complete visible wavelength ranging from 460 nm (blue) to 650 nm (red).


QD Sheets – Fabrication Methods

Fabrication of QD layers involves phase separation. A single QD layer is created by spin-casting the QDs mixed solution that concurrently produces mono layers.

The assembly comprises of hexagonal arrays packed closely with each other. These arrays are placed on the top of co-deposited contacts, as well as phase separation that causes Quantum Dots to separate from lower layer material.




Practical Uses

Scientists have succeeded in obtaining the emitted silicon light with the help of quantum dot concept. Formation of Quantum Dots involves the breakage of semiconductor material into atomic levels.

They also have the property of emitting different colors that are specifically applicable in the bio sensors field. The phenomenon of emission of different colors is also exploited in LEDs.


Future Prospects

Quantum dots can be actually printed on to a plastic sheet that can rolled up. And, you can allow you imagination to run wild to fancy the kind of toys that can be made with this kind of technology!

Many of the folks are even speculating that the quantum dot display technology would even wipe the LCDs out of business in the near future, and replace them totally. The chances are high that they may even challenge the OLEDs for future TV dominance.

There are many more practical applications of the Quantum Dot technology, which are being tested at the moment, such as illuminating human body in high-tech medical imaging.

At this point of time, one thing is for sure that you will get to see this technology creating uproar over the next few years.
