A Leader in Development of a New Form of Semiconductor: Quantum Dots
A semiconductor is a material that conducts electricity when stimulated or, when unstimulated, is
an insulator. Traditional semiconductors are the building blocks for most modern technologies, but
they do have a shortcoming. They lack versatility. Their optical and electronic properties can be
difficult and costly to adjust because their electronic structure can be changed only through complex
alterations of their structure.
Quantum dots are different. They are semiconductor particles so small that approximately 4,000,000
quantum dot nanocrystals can fit across the face of a penny. And their small size allows their
fundamental properties to be tuned or changed, overcoming many of the limitations of traditional
semiconductors and opening up a world of product possibilities.
EviDot® Technology
We have developed an advanced form of quantum dots - our proprietary EviDot® - which can be used to enable next-generation products across many markets.
We control the size and shape of our quantum dots through the careful selection of compound
semiconductors and other elements, along with atom-by-atom growth;
We have also perfected coatings and surfaces to make our quantum dots more durable and offer
better performance:
This adds strength to the quantum dot and prevents performance degradation;
The engineering of the quantum dot surface also creates compatibility with a range of
matrix materials, organic solvents, and water; and
We incorporate EviDot products into polymers, epoxies, silicones, sol-gels, and oxides; and
We also link EviDot products to secondary particles, molecules, and surfaces, making them
compatible with common chemistries and easily used in a wide range of applications.
We have the capability to manufacture commercial quantities of superior quality EviDots that emit
from deep blue at 490 nanometers through the visible spectrum and into the infrared;
Our CdSe, InGaP, CIGSe, CIGS, and PbS collectively have tunable emissions from 490nm [blue]
to 2300nm [infrared]; and
We are developing other semiconductor nanoparticles that may be tuned into the mid infrared
(3-5 micron emission) or potentially into the blue/UV region.
