From brighter TV screens to better medical diagnostics to more efficient solar panels, new research led by Curtin has discovered a way to attach more molecules to the surface of tiny nanocrystals, making it possible to improve everyday technology. This was a groundbreaking discovery that could lead to improvements.
Lead author Associate Professor Guofa Jia, from Curtin University’s School of Molecular Life Sciences, said the study investigated how the shape of zinc sulfide nanocrystals affects the extent to which molecules known as ligands attach to their surfaces. He said it was investigated. The full study, titled “Decoding the surface ligand density of colloidal semiconductor nanocrystals: A matter of shape,” will be published in the Journal of the American Chemical Society.
“Ligands play an important role in controlling the behavior and performance of zinc sulfide nanocrystals in a variety of important technologies,” said Associate Professor Jia.
“In a discovery that could open new possibilities for the development of smarter and more advanced devices, our research shows that compared to other shapes such as nanodots and nanorods, flattened and We found that more homogeneous particles allow more ligands to bind tightly.
“By tuning the shape of these particles, we were able to control how they interact with their surroundings and make them more efficient for a variety of applications. From brighter LED lights and screens to The ability to control particles in a variety of applications, from more efficient solar panels to more detailed medical imaging, has the potential to revolutionize product efficiency and performance.”

Associate Professor Jia said the discovery could improve the performance of devices known as optoelectronics that generate or use light to perform functions.
“Optoelectronics are important in many modern technologies, including telecommunications, medical devices and energy production,” said Associate Professor Jia. “The ability to efficiently manipulate light and electricity is central to advances in faster, more efficient, and more compact electronic systems.
“These include LEDs, which convert electricity into light and are used in everything from light bulbs to TV screens, and solar cells, which convert light into electrical energy and harness sunlight to power devices. Contains.
“Other devices that could be advanced by this discovery include photodetectors, such as cameras and sensors, that sense light and convert it into electrical signals, and fiber optic communications, which convert electrical signals to light for data transmission. Includes laser diodes used in
