NANOCRYSTAL LIGHTING

 
Our goal is to commercialize products based upon the 'Quantum Confined Atom' (QCA) for all applications in the field of lighting. In order to have efficient lamps, we plan to develop nanophosphors that will generate efficient white light under UV excitation. Our recent discovery has unequivocally demonstrated that in QCA based nanomaterials, the efficiency of the light emanating from a single caged atom (ion) is the highest when the particle size is less than 5nm. As the size decreases from 10 nm to 2 nm, the light from the caged atom increases non-linearly.

These nanophosphors of size range 2 to 5 nm, when properly incorporated in a clear polymer provides efficient, transparent and high-index nano-composite materials that down-convert UV-light emitting diodes to white solid state lamps. The engineering of an atom (ion) in the nano-regime has allowed us to significantly change the paradigm of designing new phosphors and lenses for all lamps.

The control of refractive index with use of QCA based nanophosphors is also expected to impact all optical, transparent materials where high refractive index is desirable, such as optometry, specialty glass etc.
