Cracked and blurry phone screens could someday be a thing of the past, suggests a new study from the University of Cambridge and the University of Queensland, Australia.
The international team of researchers has developed technology for next-generation composite glass, for use in lighting LEDs, smartphones, TVs and computer screens.<\/p>\n\n\n\n
The materials are based on materials called lead-halide perovskites, which can trap light and store energy, like miniature solar panels, says University of Cambridge in a press release<\/a>. <\/p>\n\n\n\n The results, published in the journal Science<\/em>, could enable the manufacture of glass screens that are less prone to cracking, but also deliver crystal clear image quality.<\/p>\n\n\n\n The results are a step forward in perovskite nanocrystal technology as previously, researchers were only able to produce this technology in the bone-dry atmosphere of a laboratory setting.<\/p>\n\n\n\n \u201cThese nanocrystals are extremely sensitive to light, heat, air and water \u2013 even water vapour in our air would kill the current devices in a matter of minutes,\u201d said Dr Jingwei Hou from the University of Queensland (UQ), the paper\u2019s first author.<\/p>\n\n\n\n The 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 stabilising the materials, enhancing their efficiency and preventing the toxic lead ions from leaching out from the materials.<\/p>\n\n\n\n \u201cIt was surprising to see the retention of the high temperature functional form in the glass,\u201d said co-senior author\u00a0Dr Thomas Bennett\u00a0from Cambridge\u2019s Department of Materials Science and Metallurgy. \u201cThis is an example of how fundamental science leads to fantastic discoveries and a possible real-life application of metal-organic framework glasses.\u201d<\/p>\n\n\n\n The researchers say the technology is scalable and opens the door for many potential applications.<\/p>\n\n\n\n \u201cAt present QLED or quantum dot light-emitting diode screens are considered the top performer for image display and performance,\u201d said Hou. \u201cThis research will enable us to improve on this nanocrystal technology by offering stunning picture quality and strength.\u201d<\/p>\n\n\n\n \u201cNot 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.\u201d said co-author Professor Vicki Chen, also from UQ. \u201cThis discovery opens up a new generation of nanocrystal-glass composites for energy conversion and catalysis.\u201d<\/p>\n\n\n\n The researchers say that a lot of optimisation work still needs to be carried out before any products based on the material could be made commercially available. \u201cThere are a huge amount of different combinations and it\u2019s definitely going to be a big effort to determine which components seem to give the best combinations,\u201d said Bennett.<\/p>\n\n\n\n The research is a collaborative effort from UQ, the University of Leeds, Universit\u00e9 Paris-Saclay and the University of Cambridge.<\/p>\n\n\n\n Also interesting: <\/em><\/strong>Why glass is so difficult to imitate for solar panels<\/a><\/p>\n","protected":false},"author":2084,"featured_media":315906,"template":"","meta":{"_acf_changed":false,"advgb_blocks_editor_width":"","advgb_blocks_columns_visual_guide":""},"categories":[8553],"tags":[43684,25579,23839],"location":[55977],"internal_archives":[],"class_list":["post-315905","selected","type-selected","status-publish","has-post-thumbnail","hentry","category-digital","tag-glass","tag-led-en","tag-smartphones","location-united-kingdom"],"blocksy_meta":[],"acf":[],"featured_img":"https:\/\/ioplus.nl\/archive\/wp-content\/uploads\/2022\/04\/low-res20210930-jingweihouphotoshoot6-1.jpg","coauthors":[],"author_meta":{"author_link":"https:\/\/ioplus.nl\/archive\/author\/mauro-mereu\/","display_name":"Mauro Mereu"},"relative_dates":{"created":"Posted 5 years ago","modified":"Updated 5 years ago"},"absolute_dates":{"created":"Posted on November 1, 2021","modified":"Updated on November 1, 2021"},"absolute_dates_time":{"created":"Posted on November 1, 2021 5:30 pm","modified":"Updated on November 1, 2021 5:30 pm"},"featured_img_caption":"\u00a9 The University of Queensland","tax_additional":{"category":{"linked":["Digital<\/a>"],"unlinked":["Digital<\/span>"],"slug":"category","name":"Categories"},"post_tag":{"linked":["glass<\/a>","LED<\/a>","Smartphones<\/a>"],"unlinked":["glass<\/span>","LED<\/span>","Smartphones<\/span>"],"slug":"post_tag","name":"Tags"},"language":{"linked":["EN<\/a>"],"unlinked":["EN<\/span>"],"slug":"language","name":"Tags"},"post_translations":{"linked":[],"unlinked":[],"slug":"post_translations","name":""},"location":{"linked":["United Kingdom<\/a>"],"unlinked":["United Kingdom<\/span>"],"slug":"location","name":"Locations"},"internal_archives":{"linked":[],"unlinked":[],"slug":"internal_archives","name":"Internal Archives"}},"series_order":"","_links":{"self":[{"href":"https:\/\/ioplus.nl\/archive\/wp-json\/wp\/v2\/selected\/315905","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/ioplus.nl\/archive\/wp-json\/wp\/v2\/selected"}],"about":[{"href":"https:\/\/ioplus.nl\/archive\/wp-json\/wp\/v2\/types\/selected"}],"author":[{"embeddable":true,"href":"https:\/\/ioplus.nl\/archive\/wp-json\/wp\/v2\/users\/2084"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/ioplus.nl\/archive\/wp-json\/wp\/v2\/media\/315906"}],"wp:attachment":[{"href":"https:\/\/ioplus.nl\/archive\/wp-json\/wp\/v2\/media?parent=315905"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/ioplus.nl\/archive\/wp-json\/wp\/v2\/categories?post=315905"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/ioplus.nl\/archive\/wp-json\/wp\/v2\/tags?post=315905"},{"taxonomy":"location","embeddable":true,"href":"https:\/\/ioplus.nl\/archive\/wp-json\/wp\/v2\/location?post=315905"},{"taxonomy":"internal_archives","embeddable":true,"href":"https:\/\/ioplus.nl\/archive\/wp-json\/wp\/v2\/internal_archives?post=315905"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}Creating better glasses<\/h3>\n\n\n\n
