Synthesis of quantum dots emitting blue light is our priority.

Blue light emitters are essential in 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 an optoelectrical perspective. That’s why – because of the dynamic growth in this segment of the market – new, better materials that can emit blue light need to be introduced.

Blue light spectrum

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 440 nm wavelength.
Currently, our priority is the development of the PureBlue.dots product with a maximum emission of 455 nm. We are constantly working to improve the parameters of quantum dots and to adapt them to the needs of our customers. The product is being developed for use in electroluminescence and light conversion.

Specifications of our materials
