Curtin University researchers have discovered tiny 'greener' nanocrystals that can be manipulated to produce high-quality pictures and lighting in electronic devices such as televisions.

The research, published in the Journal of Physical Chemistry Letters, found that the thickness of the tiny rectangular-shaped nanocrystals, called nanoplatelets, could be controlled with atomic precision, and can be used to improve the brightness and colour performance displayed on an LCD screen.

Researcher - ARC - DECRA - Fellow - Dr

Lead researcher ARC DECRA Fellow Dr. Guohua Jia, from Curtin's School of Molecular and Life Sciences and the Curtin Institute for Functional Molecules and Interfaces, said manufacturers were constantly searching for products with unprecedented picture quality given the high demand and competition in the electronics industry.

"A popular choice by consumers are quantum dot light emitting diodes (QLED) televisions, which use quantum dots to produce better brightness and a wider colour spectrum. The dots act like an activation layer when applied on a blue LED backlight, producing a more saturated and wider colour gamut," Dr. Jia said.

Research - Picture - Quality - Devices - Form

"Our research explored whether we could improve the picture and lighting quality in similar electronic devices by creating a new form of nanocrystal. We were able to create these by using a wet-chemical, 'bottom-up' method, in which chemicals in their ionic phase react in a solvent in...
