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
