Description:

Area of Interest 3: High temperature, efficient,
long-life phosphors,
luminescent materials for wavelength conversion and encapsulants

Near term SSL general illumination products are expected to be designed
around
near UV or blue emitting LEDs that capture a portion of their
monochromatic
emissions with a yellow phosphor that in turn converts some of the pump
radiation into a broader spectrum, whose combined emissivity approximates
white
light of good color and spectral power. Although many materials that are
currently used for these purposes are reasonably efficient, even more
efficient
phosphors and/or luminescent materials may bring an immediate increase in
device efficiency. For example, multi-photon processes can produce
quantum
yields in excess of unity even for relatively low energy excitations such
as
380 nm. Suitable hosts and materials systems need to be developed to
advance
these to practical, energy efficient devices for general illumination
products. Applied research is sought in this area that investigates novel

phosphors and/or luminescent material synthesis and blends.

Within down-conversion approaches to white light generation, more
efficient
(>95%), stable (100,000 hrs), high-temperature (>150 /degrees/ C),
environmentally
friendly phosphors with no dissipative optical absorption or scattering
will
need to be developed. Novel approaches are also needed and sought for the

synthesis and processing of novel conversion materials, including, but not

limited to nanocrystalline semiconductors, photonic lattices, quantum
dots,
organic coordination-compound phosphors, phosphor blends or slurries, and
coated phosphors.

High-drive, high-lumen output LED devices place demanding performance
requirements on encapsulation materials. Future encapsulation materials
for
high-power general illumination products will need to have an index >1.6,

high transmission (>80%) through thick layers throughout the visible
spectrum
(440-650 nm), UV filtering and resistance, low H2O permeability for up to
100,000 hours, and withstand high processing and operation temperatures
(100-150 /degrees/ C). New approaches and materials are sought.
