We were the first to successfully create it using cost-effective raw materials such as urea with simple processing,&#8221; said Qu Songnan, an associate researcher at Changchun Institute of Optics, Fine Mechanics and Physics, the Chinese Academy of Sciences, which leads the research.<\/p>\n<p>Qu said the rare earth has a long lifespan which reduces the speed of Li-Fi transmission. However, F-CDs enjoy the advantage of faster data transmission speeds.<\/p>\n<p>In previous studies, carbon dots were limited to the emission of lights such as blue and green. The new nanomaterial that Qu&#8217;s team has developed can emit all light visible to the human eye, which is a breakthrough in the field of fluorescent carbon nanomaterial.<\/p>\n<p>Qu said this is significant for the development of Li-Fi, which he expects to enter the market in just six years.<\/p>\n<p>A 2015 test by a Chinese government ministry showed that Li-Fi can reach speeds of 50 gigabytes per second, at which a movie download can be completed in just 0.3 seconds.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>CHANGCHUN\u00a0&#8212; Chinese scientists have made a breakthrough in creating full-color emissive carbon dots (F-CDs), which brings them one step closer &hellip;<\/p>\n","protected":false},"author":33,"featured_media":115588,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[5],"tags":[25901,25902,25897,25900,25899,25898,25904,25903,21451],"class_list":["post-121083","post","type-post","status-publish","format-standard","has-post-thumbnail","category-technology","tag-changchun-institute-of-optics","tag-fine-mechanics-and-physics","tag-full-color-emissive-carbon-dots","tag-led-bulbs","tag-li-fi","tag-light-fidelity","tag-qu-songnan","tag-the-chinese-academy-of-sciences","tag-wi-fi","mauthors-xinhua","mauthors-philippine-news-agency"],"_links":{"self":[{"href":"https:\/\/canadianinquirer.net\/v1\/wp-json\/wp\/v2\/posts\/121083","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/canadianinquirer.net\/v1\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/canadianinquirer.net\/v1\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/canadianinquirer.net\/v1\/wp-json\/wp\/v2\/users\/33"}],"replies":[{"embeddable":true,"href":"https:\/\/canadianinquirer.net\/v1\/wp-json\/wp\/v2\/comments?post=121083"}],"version-history":[{"count":0,"href":"https:\/\/canadianinquirer.net\/v1\/wp-json\/wp\/v2\/posts\/121083\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/canadianinquirer.net\/v1\/wp-json\/wp\/v2\/media\/115588"}],"wp:attachment":[{"href":"https:\/\/canadianinquirer.net\/v1\/wp-json\/wp\/v2\/media?parent=121083"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/canadianinquirer.net\/v1\/wp-json\/wp\/v2\/categories?post=121083"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/canadianinquirer.net\/v1\/wp-json\/wp\/v2\/tags?post=121083"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
