Rare Earth Nano-Materials
The
research group focuses on the synthesis, processing,
consolidation and applications of rare earth
nano-particles. The group has developed various
methods to synthesize these nano-particles in
the oxide, nitride, sulfate and carbide forms.
These methods include sol gel, precipitation
(direct, co-precipitation, gel precipitation
etc), plasma spraying (direct current and radio
frequency), flame spraying (hydrolysis and pyrolysis)
and electrostatic atomisation.
Several
consolidation / application methods are also
being studied and developed, and these include
tape casting (aqueous and non-aqueous), spray
drying, sputtering and spin coating.
Typical
research areas include gadolinium oxide-doped
cerium oxide nano-particles for mid-temperature
solid oxide fuel cells, ITO nano-particles for
OLED and sputtering target, Y/Eu nano-particles
for plasma displays. They also include nano-phosphors
for RGB and white LEDs, Boron-Neodymium for magnets,
and barium sulphate and boron carbide nano-particles
for medical and defence applications respectively.
Rare earth nano-particles for applications in
MLCCs and MLCPs for microelectronics are currently
being studied.
The
group collaborates actively with AMR Technologies
Inc. (Canada), the Defence Science and Technology
Agency (DSTA), Johnson & Johnson, University
of California Los Angeles (UCLA) and University
of Cambridge (UK).
