Quantum Materials Tetrapod Quantum Dots Break Kasha's Rule: Enhanced Performance Enables Commercialization of Novel Discovery
Date:6/6/2013

SAN MARCOS, Texas, June 6, 2013 /PRNewswire/ -- By Quantum Materials Corporation (OTCQB:QTMM) – Since 1950, Kasha's  Rule 1, a principle of photochemistry,  held true that if a source of light excited a molecule enough, the molecule would fluoresce in a single color.  In 2011, the Alivasatos group at DOE's Lawrence Berkeley National Laboratory, using tetrapod quantum dots, broke Kasha's rule2 by causing them to emit two separate colors instead of just one. This dual emission is possible because the tetrapod's core and arms can separately emit at different wavelengths, and this discovery finds potential in many new advances in optics and nanobio applications.

Quantum Materials Corp. (QMC) is delivering tetrapod quantum dots to a client studying dual emission effects in sensitive force sensing environments. Dual-emitting tetrapod QD sensors can measure very minute stresses such as those of a heartbeat by reading the changing variance of luminescence response emitted as the tetrapod quantum dots arms bend. Nano-probes of this type are poised to be a platform technology providing optical readout for many other biomechanical processes.  This unique ability of the tetrapod quantum dot helps it to outshine the more common spherically shaped quantum dot.

QMC's patented synthesis allows precise control of tetrapod quantum dot composition, size of QD core, length of arms, and arm thickness. This ability to design the tetrapod characteristics allows optimization to control the tetrapod's reaction to stress and thereby tune the light emissions for different applications. QMC VP of R&D David Doderer remarked, "We are proud  to stand out as the singul
