When does using quantum dots make sense?
Quantum dots are the best solution whenever you’re looking for a material that can emit, absorb, or convert high-quality, stable (long-lasting) light while also providing additional device features. These includes flexibility, printability and transparency.
What does QNA Technology do?
What sets us apart is the way we approach creating nanomaterials designed for industrial uses. At QNA Technology we do a lot more than develop solutions or procedures for synthesis of quantum dots. We’re also working on modifying the surface of quantum dots so that they can be easily applied to the solutions being used by our clients. Additionally, we’ve focused our efforts on the formulation of quantum inks which contain quantum dots – this makes it possible for our clients to print semiconductors on any surface and using the printing technology of their choice.
What are quantum dots?
Quantum dots are semiconductor nanocrystals about 10 nm in size. They are composed of a inorganic core and shell which determine the optical quality of material as well as an organic coating which determines the environment in which dots can be placed.
Why replace other materials which emit light with quantum dots?
Quantum dots can be used instead of organic dyes. Their advantage results from their inorganic, crystal-clear nature and the quantum properties they can deliver to a nanoscopic environment.
How can our quantum dots be applied?
Our technology makes is possible to manufacture dot semiconductors in a colloidal format – one where the physicochemical properties of the solution produced can be defined by the user. This innovation makes it possible to apply quantum dots using most of the methods which work in the case of organic materials.
Our dots can be delivered in polar and nonpolar solvents as well as in the form of ink which makes it possible to print semiconductors on a range of different surfaces – including those that are flexible or even transparent.
Synthesis of quantum dots emitting blue light is our priority.
Blue light emitters are essential in any and every visual application [displays] as well as those that generate white light [lighting] because the reproduction of colors in these applications requires a RGB pallet. The blue emitter or electroluminescent diode (LED) are the most important element [source of light] in these kind of devices.
Materials emitting blue light are among the most difficult to produce, especially when we’re looking to so do while maintaining environmentally friendly norms and making health of potential users a crucial concern.
The blue organic dyes currently being used have specifications which are far from optimal from a optoelectrical perspective. That’s why – because of the dynamic growth currently being experienced in this segment of the market – new, better materials that can emit blue light need to be introduced.
Blue light is defined as having a wavelength of approximately 390 to 490 nm. At QNA Technology we were able to produce DeepBlue.dots® – which do not contain any heavy metals or rare earth elements (in accordance with the EU’s RoHS Directive) and emit on 425 nm wavelength.
Our current priorities are focused on developing dots emitting on the 450-470 nm wavelength. These PureBlue.dots® will also be manufactured in accordance the EU’s RoHS Directive.
Specifications of our materials
Research and development of PureBlue.dots® – a new product in the form of a colloidal solution made of quantum dots that are characterized by a limited toxicity and can emit blue light on a wavelength that is safe for the human eye. These features are particularly important and desired by the display industry.
