Two U.S. DOE SBIR Grants awarded to SSL Technology

The U.S. Department of Energy Office of Science and Basic Energy Sciences has awarded two Small Business Innovation Research (SBIR) Phase II Release 1 grants related to solid-state lighting. Phase II SBIR grants are awarded to successful Phase I Release 1 recipients. The FY16 Phase II Release 1 awards—each worth about US $1 million and 24 months in duration—will explore the technical merit or feasibility of an innovative concept or technology.

The two Phase II Release 1 awards related to SSL are briefly described below:

SBIR Recipient: PhosphorTech Corporation (Kennesaw, GA)
Title: Plasmonic-enhanced High Light Extraction Phosphor Sheets for Solid State Lighting
Summary: This project aims to maximize the luminous efficacy of a phosphor down-converting LED system using a combination of high-quantum-yield red phosphors, surface plasmon resonance, and enhanced light-extraction efficiency, which is expected to yield more than a 42% improvement in efficacy while reducing the amount of phosphor material by 50%, which will lower costs. These improvements will enable a wider range of new energy-efficient applications in LED packaging serving the general-illumination industry.

SBIR Recipient: Lumisyn, LLC (Rochester, NY)
Title: Nanocrystal-based Phosphors with Enhanced Lifetime Stability
Summary: This project aims to synthesize compositionally novel nanocrystals that will maintain high efficiency simultaneously at high temperatures and optical flux, enabling the production of high-efficiency, long-lifetime, on-chip, narrow-wavelength (<50 nm) phosphors for phosphor-converted (pc) LEDs manufactured by a wide range of companies worldwide. Colloidal nanocrystal down-converting phosphors are not currently used in commercial pcLED products because they are thought to be inherently of low efficiency and poor stability when placed on chip.
