Overview

Research Interests

Fundamental luminescent materials
Visible emission from oxide phosphor materials YAG, Zn2Si04:Mn, Ga203:Eu and related compounds is being studied under electroluminescence and photoluminescence. Nanoparticles of these phosphors are synthesized by bottom-up approaches for use in microLEDs and luminescent solar concentrators. Thin films of these oxide phosphors may be grown by RF sputtering on glass and ceramic substrates.

This work shows for the first time that powders and thin films of oxide phosphors can achieve bright electroluminescent emission using nanowire and thin film structures.

Seamless Liquid Crystal Display Technology
A new type of display using a liquid crystal imaging system illuminated by light emitting diodes achieves an arbitrarily large and seamless full colour display suitable for public displays in the form of an electronic poster. New optical components and software are being developed to optimize the performance of this system. 

The key materials requirement is a projection screen “fabric” that must scatter light with directional optical properties not available from commercially available product.   Work to engineer materials in the form of laminated particle assemblies with unique optical properties is on-going and involves creative use of polymer films and transparent polymer particles.
