Evident Technologies Launched Nanotechnology-Based LED Products

Evident Technologies Inc. announced the commercial availability of its Evidot LED products based on semiconductor nanocrystal technology. Whereas traditional LEDs are available in a limited set of standard colors (blue, green, red, etc.), Evident’s new products enable LEDs to emit any color, including high-quality white light (see video).

“This nanotechnology breakthrough enables us to make LEDs of any color without requiring complex electronic controls, liberating the end-user or designer to dream up many new applications,” stated Clint Ballinger, CEO of Evident Technologies. “The limitations of designing a product around the existing, traditional colored LED are removed.”

Applications that could utilize this new product line include signage to make specific brand colors, LCD backlights to increase display color ranges, and high color rendered white LEDs in a wide range of color temperatures. The new products are available in lamp-type or surface mounted LED packages.

“As the world becomes increasingly mindful of the need to conserve energy, LED use has grown tremendously,” said Dave Duncan, COO Evident Technologies. “Now we are bringing new colors to these efficient light sources.”

How Quantum Dots Work: A Special Class of Semiconductors
Quantum dots, also known as nanocrystals, are a special class of materials known as semiconductors, which are crystals composed of periodic groups of II-VI, III-V, or IV-VI materials. Semiconductors are a cornerstone of the modern electronics industry and make possible applications such as the Light Emitting Diode and personal computer.

Semiconductors derive their great importance from the fact that their electrical conductivity can be greatly altered via an external stimulus (voltage, photon flux, etc), making semiconductors critical parts of many different kinds of electrical circuits and optical applications. Quantum dots are a unique class of semiconductor because they are so small, ranging from 2-10 nanometers (10-50 atoms) in diameter. At these small sizes, materials behave differently, giving quantum dots unprecedented tunability and enabling never before seen applications to science and technology.
