Cracked phone screens could become a thing of the past thanks to breakthrough research by a global team of scientists
Diamond’s electron Physical Science Imaging Centre (ePSIC) was used in a study that has unlocked the technology to produce next-generation composite glass for lighting LEDs as well as smartphone, television and computer screens.
The research was recently published in the journal Science and was carried out by an international collaboration involving scientists and engineers from the University of Queensland, University of Leeds, University of Cambridge and Université Paris-Saclay. The findings will enable the manufacture of glass screens that are not only unbreakable but also deliver crystal clear image quality.
The study is focused on nanocrystal materials known as lead halide perovskites, which are promising candidates for light emitting diodes. A powerful electron microscope at ePSIC allowed the team to study the structure of this material. The breakthrough has been the ability to stabilise a particular crystal at room temperature.
