grant allows Evident to develop advanced quantum-dot
based anti-counterfeiting materials. Evident Technologies
announced that it has received a Phase 1 SBIR (Small
Business Innovation Research) grant to develop advanced
anti-counterfeiting materials based on its proprietary
quantum dot technology. The award is under National
Science Foundation (NSF) SBIR 0441676.
Work
under the project, which is scheduled for completion
in July 2005, will combine Evident's recent advances
in quantum dots and micro-resonant structures to create
unique spectral barcode tags for high security applications.
Quantum dots are novel semiconductors with unique
optical emission characteristics. Micro-resonant structures
are optical devices engineered to allow very specific
colors to be transmitted. By combining these two technologies,
a wide variety of security tags can be created to
produce unique spectral-bar codes. The unique interaction
between the two technologies creates security features
that are nearly impossible to counterfeit, duplicate
or reverse engineer.
“By
combining fl uorescing quantum dots with a resonant
optical structure, we believe we will significantly
advance anti-counterfeiting devices” stated Clint
Ballinger, CEO of Evident Technologies. “Our goal
under this contract is to produce advanced quantum
dots systems compatible with a range of inks, UV curable
epoxies, and polymers used on currencies and other
documents. This new technology, with its complexity
and breadth of application, should provide additional
deterrents in personal and industrial security and
counter terrorism.”
