Their vibrant fluorescence under ultraviolet light was captured on a phone camera by Bidyut Das, a postdoctoral research associate in <a href=\"https:\/\/samirkumarsarkar1.wixsite.com\/my-site-1\/about-1\" rel=\"nofollow noopener\" target=\"_blank\">Samir Kumar Sarkar\u2019s laboratory<\/a> at the Indian Institute of Technology Guwahati. The lab\u2019s research focuses on creating luminescent organic materials. These particular crystals are made from a compound that has an electron-accepting segment flanked by two electron-donating segments. The molecules pack in such a way that they restrict each other\u2019s movement within the crystal lattice. This confinement keeps the molecules from releasing energy through nonluminescent means and leads to much brighter fluorescence, a useful trait for applications such as organic light-emitting diodes.<\/p>\n<p class=\"article-content\">Submitted by Bidyut Das<\/p>\n","protected":false},"excerpt":{"rendered":"These rigid rod-shaped crystals, measuring about 0.5 mm in width and a few millimeters long, have an outsize&hellip;\n","protected":false},"author":2,"featured_media":632504,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[7],"tags":[310116,14218,45502,310117,397,9665,111,139,69,22965,63333,147],"class_list":["post-632503","post","type-post","status-publish","format-standard","has-post-thumbnail","category-science","tag-chempics","tag-crystal","tag-fluorescence","tag-luminophore","tag-materials","tag-molecular-electronics","tag-new-zealand","tag-newzealand","tag-nz","tag-optoelectronics","tag-phosphorescence","tag-science"],"_links":{"self":[{"href":"https:\/\/www.newsbeep.com\/nz\/wp-json\/wp\/v2\/posts\/632503","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.newsbeep.com\/nz\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.newsbeep.com\/nz\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/nz\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/nz\/wp-json\/wp\/v2\/comments?post=632503"}],"version-history":[{"count":0,"href":"https:\/\/www.newsbeep.com\/nz\/wp-json\/wp\/v2\/posts\/632503\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/nz\/wp-json\/wp\/v2\/media\/632504"}],"wp:attachment":[{"href":"https:\/\/www.newsbeep.com\/nz\/wp-json\/wp\/v2\/media?parent=632503"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.newsbeep.com\/nz\/wp-json\/wp\/v2\/categories?post=632503"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.newsbeep.com\/nz\/wp-json\/wp\/v2\/tags?post=632503"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
