Unlocking the Technology That Will Allow for the Production of Unbreakable Composite Glass Screens


Cracked phone screens may soon be a thing of the past, thanks to groundbreaking research carried out at The University of Queensland.


Professor Lianzhou Wang and Professor Vicki Chen from the University of Queensland led a global research team that successfully unlocked the technology for producing next-generation composite glass for use in LED lighting, smartphone, television, and computer screens.


The findings will pave the way for the development of glass screens that are not only impenetrable but also capable of producing images with exceptional clarity.


In his statement, Dr. Hou stated that the discovery represents a significant advancement in the field of perovskite nanocrystal technology, as previously, researchers could only produce this material in a bone-dry laboratory setting.


"The emitting materials are composed of nanocrystals of lead-halide perovskites," he explained. "They have the ability to harvest sunlight and convert it to renewable electricity, which is critical for the development of low-cost, high-efficiency next-generation solar cells as well as a variety of promising applications such as lighting," according to the researchers.


"Unfortunately, these nanocrystals are extremely sensitive to light, heat, air, and water – even the water vapor present in our atmosphere would cause the current devices to fail within seconds of being exposed to it.


"We developed a method for wrapping or binding nanocrystals in porous glass with the help of a team of chemical engineers and material scientists.


In order to stabilize the materials and increase their efficiency while preventing toxic lead ions from leaching out, this process is essential.


Dr. Hou stated that the technology was scalable and could be used for a wide range of applications.


At the moment, QLED or quantum dot light-emitting diode displays are widely regarded as the best performer in the industry in terms of image display and performance, according to Mr. Wang.


"Through this research, we will be able to improve the image quality and strength of this nanocrystal technology," says the researcher.


Professor Vicky Chen expressed her excitement about the development.


According to Professor Chen, "Not only can we strengthen these nanocrystals, but we can also tune their opto-electronic properties to produce extremely efficient light emitters and highly desirable white light LEDs."


"This breakthrough paves the way for the development of a new class of nanocrystal-glass composites for energy conversion and catalysis," says the team.
