ATHENS, GA – The University of Georgia Research Foundation Inc. and the University of Puerto Rico have granted an international, nonexclusive license for a portfolio of glow-in-the-dark pigments that can be designed to emit light in any color of the visible spectrum for nearly a day. Performance Indicator LLC, of Lowell, MA, has acquired the license.
By exploiting the phenomenon of energy transfer, the new technology can produce long-lasting glow in any color, including blue, green or red, and in tints and hues, such as pink, without extensive modification to the composition of the materials.
The seven phosphors included in this patent portfolio are simple to manufacture and environmentally safe. They do not contain sulfur, radioactive materials or lead, and can be used in a multitude of consumer and industrial applications.
The license allows Performance Indicator LLC to adapt, patent and market color-change or indicator technologies for a variety of industrial and consumer applications and to import, manufacture and sell the phosphors.
