Dotz GQDs are suitable for use in the conventional QD market (healthcare, displays, lighting and energy related), but it is in the unconventional QD markets that Dotz Nano makes its breakthrough, namely the low cost high volume end markets.
Low end markets consist of lower priced products. In this case these low-end markets, due to the high price of QDs, could not sustain using QDs in their production processes, but are accessible to Dotz Nano, due to the lower costs of coal derived GQDs. Applications such as:


Graphene Quantum Dots (GQDs) are tiny crystals that have the ability to convert light/energy from one color to another color quite effectively. The GQDs can be integrated into a film replacing a diffuser film. The current cutting-edge display markets are using Inorganic QDs which are characterized by several challenges, among them: heavy metal toxicity, limited use of blue colored QDs and high prices. Graphene Quantum Dots is a clear alternative which will allow manufacturers to produce high quality displays and address these challenges.

Bio Imaging

Graphene Quantum Dots (GQDs) have distinct advantages over traditional fluorescent organic dyes and heavy metal QDs in terms of tunable emission spectra, signal brightness, photo stability, low cost and most important non-toxicity. These unique features enable the development of a wide range of safe and efficient solutions in the in-vitro and in the future, the in-vivo imaging market.

Anti-Counterfeiting Applications

used in anti-counterfeiting and monitoring applications such as currency, casino chips, medicinal packaging etc. Specifically the development of GQDs that can be used to monitor and provide anti-counterfeiting mechanisms for use in liquids, such as crude oil, fuels and petrol, olive oil, palm oil and wines.

Pigments and Dyes

Using GQDs as a brightening agent in Pigments and Dyes. Pigments that are used in clear and pigmented lacquers, paints, molded thermoplastics, films and sheets, printing inks, synthetic leather, ultraviolet tracer, photo processing solutions, adhesives, fibers.


Color-correcting or brightening additive in advanced cosmetic formulas (shampoos, conditioners, eye makeup). An additional application is to formulas for washing and conditioning grey or blonde hair, where the brightener can not only increase the luminance and sparkle of the hair, but can also correct dull, yellowish discoloration without darkening the hair. Some advanced face and eye powders contain optical brightener micro spheres that brighten shadowed or dark areas of the skin, such as “tired eyes”.


carbon and graphene quantum dots (CDs, GQDs) have attracted tremendous attention to their potential for biological, optoelectronic, and energy related applications. Among these applications, bio-imaging has been intensively studied, but optoelectronic and energy devices are rapidly rising. Recent exciting progresses on CD- and GQD-based optoelectronic and energy devices, such as light emitting diodes (LEDs), solar cells (SCs), photo-detctors (PDs), photo-catalysis, batteries, and supercapacitors. In the display market (TV’s, computer and tablet displays) red and green metallic quantum dots are used to produce films for use in Quantum Dot TV’s. Blue QDs are not used due to problematic properties which is where Dotz Nano’s Blue QDs excel.

Optical brighteners

The tendency of many organic materials to yellow is due to degradation by UV or visible light. The breakdown products absorb blue light, giving a yellow appearance in daylight. Products that absorb UV light and then transmit it in the blue range can be used to counter this effect. They also make whites appear ‘brighter’ to the human eye. Optical brighteners are designed to brighten colors or mask yellowing in lacquers, paints, inks, plastics, photo-processing solutions and fibers. They work via a fluorescent mechanism, absorbing light in the UV spectrum and emitting it in the blue range of the visible spectrum, resulting in a brighter, fresher appearance. Optical brightening agents (OBAs), fluorescent brightening agents (FBAs) or fluorescent whitening agents (FWAs) are chemical compounds that absorb light in the ultraviolet and violet region (usually 340-370 nm) of the electromagnetic spectrum, and re-emit light in the blue region (typically 420-470 nm) by fluorescence. Fluorescent emission is a short-lived period of light emission by a fluorophore, unlike phosphorescence, which is long-lived. These additives are often used to enhance the appearance of color of fabric and paper, causing a “whitening” effect; they make intrinsically yellow/orange materials look less so, by compensating the deficit in blue and purple light reflected by
the material, with the blue and purple optical emission of the fluorophore. Examples of the uses are:


most toothpastes today contain optical brighteners to improve the dental whiteness
