Mar 11, 2016: Solid-state lighting (SSL) technology has received two Small Business Innovation Research (SBIR) phase II release 1 grants from the US Department of Energy (DoE), Office of Science and Basic Energy Sciences. Successful phase I release 1 recipients’ have been awarded the phase II SBIR grants.
The financial year 2016 phase II release 1 awards have a worth of US $1 million each with a time span of 2 years. These awards will assist SSL technology to explore the technical merits or feasibility of the said technology. The SSL phase II release 1 award details are explained below:
SBIR recipient: PhosphorTech Corporation (Kennesaw, GA)
Project title: Plasmonic-enhanced high light extraction phosphor sheets for SSL technology
Project summary: The project’s target is to maximize the luminous efficacy of a phosphor down-changing LED system with a combination of high-quantum-yield red phosphors, enhanced light extraction efficiency and surface plasmon resonance. This will yield more than 42% in efficacy improvement while reducing the amount of phosphor material by 50%, thus lowering the costs. These major improvements will enable a varied range of new energy-efficient applications in LED packaging to serve the general-illumination industry.
SBIR recipient: Lumisyn, LLC (Rochester, NY)
Project title: Nanocrystal-based phosphors with enhanced lifetime stability
Project summary: This project aims to extract compositionally novel nanocrystals that will maintain high efficiency alternatively at high temperatures and optical flux. This enables the production of long-lifetime, on-chip, high-efficiency, narrow-wavelength (<50 nm) phosphors for phosphor-converted (pc) LEDs made by multiple companies worldwide. Colloidal nanocrystal down-converting phosphors are not used these days in commercial pcLED products due to low efficiency and poor stability when placed on the chip.
