They then use mechanical force to turn it into glass. They take a raw material, like zinc, and use an organic molecule that can bind to zinc. "Perovskites are a very functional material, but because of their sensitivity to almost everything they need to be put into the glass." "This process is the key to stabilising the materials, enhancing efficiency and inhibiting the toxic lead ions from leaching out. "So our team of chemical engineers and material scientists then developed a revolutionary process to wrap or bind the nanocrystals in porous glass," he said. To address the breakage issue, he turned to a mineral called perovskite, a calcium titanium oxide crystal.īut Dr Hou said the researchers found perovskite "nanocrystals" were extremely sensitive to light, heat, air and water. He said the glass currently used in phones was very dense and inflexible. "When I came into this, I thought 'wouldn't it be amazing if we could fix the problem getting the screen more flexible and more durable at the same time.'"
