QNA.dots

We are the producer of blue light quantum dots, which are desirable on markets of advanced light-using technology

We are developing Deep Blue Light Emitting quantum dots (QNA-DB.dots)

Our QNA-DB.dots have already superior stability and very good spectral characteristics. QNA-DB.dots can be delivered in various solvents, both polar and nonpolar

Advantages of QNA.dots

  • Heavy metal free

    The global QD market is transitioning from cadmium based to heavy-metal-free QDs. Our Deep Blue quantum dots are fully RHoS compliant

  • High quality & large quantities

    We’re developing a unique technology based on continuous flow. This makes it possible to produce large quantities without compromising their quality

  • Good stability

    Contrary to organic dyes, quantum dots are very resistant to external factors like UV radiation, humidity, and temperature.

  • Different solvents

    We would like to make the best and most practicable QD dots possible for our customers. As a result, our QNA.dots are available in various polar and nonpolar solvents.

  • Easy implementation

    To make the QDs deposition process optimal, QNA.dots are available in ink form, with a broad range of viscosities.

Advantages of Deep Blue Light

  • Enables reproduction of an even wider palette of colors than 450 nm dots

  • Interacts with human tissue more than 450 nm dots, but are not in the carcinogenic UV band

  • Initiates chemical reactions with many substances (dentistry, agriculture, pharmacy) where 450 nm dots turn out to be less effective

  • Stimulates receptors of the human eye better and attract attention more effectively than 450 nm dots

Applications of QNA.dots

QNA.dots in electroluminescent devices

QDs based emitters are better than classical 430 nm LED if we need:

  • to reduce size via integration
  • to reduce costs via printing
  • a transparent device
  • an elastic device

QNA.dots in security printing

Counterfeiting is a serious problem, causing billion dollar losses annually in the global economy

Our deep blue QNA.ink can be an important distinguishing feature and gives a unique fingerprint – and that’s what this industry is all about
