Nanostructured anti-reflection coatings for energy efficient LED lighting - DP150103317

Funding: 2015: $90,000
2016: $86,300
2017: $90,000

Project Member(s): Phillips, M., Ton-That, C., Ford, M.

Funding or Partner Organisation: Australian Research Council (ARC Discovery Projects)

Start year: 2015

Summary: Light emitting diode devices play a critical role in emerging technologies with important current and future applications in medicine, health, horticulture, nanotechnology, biology and photonics. The basic laws of optics, however, only allow a very small amount of light to escape their surfaces due to very strong intrinsic internal reflection. This project aims to optimally couple light by design to nanostructured metal ¿ low loss zinc oxide surface coatings to significantly improve the light extraction efficiency. These breakthroughs in nanoscience and nanotechnology will lead to enhanced LED performance, efficiency and longevity.
