A collaborative research team that included scientists from the University of Queensland (UO), the University of Leeds, Université Paris-Saclay and University of Cambridge, has developed perovskite-based composite glass that is virtually unbreakable and delivers crystal clear image quality.

UQ's Dr. Jingwei Hou said the discovery was a huge step forward in perovskite nanocrystal technology as previously, researchers were only able to produce this technology in the atmosphere of a laboratory setting as lead-halide perovskites NCs are extremely sensitive to light, heat, air and water. However, Hou said that “Our team of chemical engineers and material scientists has developed a process to wrap or bind the nanocrystals in porous glass. This process is key to stabilizing the materials, enhancing its efficiency and inhibits the toxic lead ions from leaching out from the materials.”

Dr. Hou said the technology was scalable and opened the door for many applications.

“At present QLED or quantum dot light-emitting diode screens are considered the top performer for image display and performance,” he said. “This research will enable us to improve on this nanocrystal technology by offering stunning picture quality and strength.”

Professor Vicky Chen said: “Not only can we make these nanocrystals more robust but we can tune their opto-electronic properties with fantastic light emission efficiency and highly desirable white light LEDs“.

“This discovery opens up a new generation of nanocrystal-glass composites for energy conversion and catalysis.”
