Solid-state lighting (SSL) is rapidly gaining momentum as a highly energy-efficient replacement technology for traditional lamps. However, current solid state LED devices still suffer from low efficiencies partly due to optical mismatch between the LED and phosphor materials. PhosphorTech has developed a new class of high index material with superior optical performance to the current state of the art. These patent-pending phosphors were optically designed to maximize LED light outcoupling through careful control of their optical properties (such as, refractive index, scattering, absorption, luminescence efficiency, etc.). During the Phase I project, PhosphorTech proposes to demonstrate the feasibility of large-scale production of these new phosphor materials. Phase II goal will be to mass produce these materials at the levels demanded by the future SSL market.
