This method can deliver a series of high-quality large-size organic-inorganic hybrid perovskite single crystals with different compositions, including FAPbX3 (X=I, Br), MAPbX3 (X=I, Br, Cl), MAPb (I\/Br)3, MAPb (Br\/Cl)3, MA\/FAPbX3(X=I,Br), CsPbBr3, etc., in which FAPbBr3 has a lifetime of 10199ns, about 4 times the data reported in the literature, setting the highest record for organic-inorganic perovskite single crystals with single A-site ion. This work provides a new technical method and theoretical basis for further improving the properties of organic-inorganic perovskite single crystals and potential large-scale generalized growth.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>BJUT&#8217;s Joint Research on Organic-Inorganic Perovskite Single Crystals Published on Nature Communications. <span class=\"readmore\"><a href=\"http:\/\/new.guofucourses.cn\/wordpress\/index.php\/2021\/08\/04\/perovskite-single-crystals\/\">Read More<\/a><\/span><\/p>\n","protected":false},"author":1,"featured_media":465,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":[],"categories":[5,7],"tags":[],"_links":{"self":[{"href":"http:\/\/new.guofucourses.cn\/wordpress\/index.php\/wp-json\/wp\/v2\/posts\/452"}],"collection":[{"href":"http:\/\/new.guofucourses.cn\/wordpress\/index.php\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"http:\/\/new.guofucourses.cn\/wordpress\/index.php\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"http:\/\/new.guofucourses.cn\/wordpress\/index.php\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"http:\/\/new.guofucourses.cn\/wordpress\/index.php\/wp-json\/wp\/v2\/comments?post=452"}],"version-history":[{"count":2,"href":"http:\/\/new.guofucourses.cn\/wordpress\/index.php\/wp-json\/wp\/v2\/posts\/452\/revisions"}],"predecessor-version":[{"id":457,"href":"http:\/\/new.guofucourses.cn\/wordpress\/index.php\/wp-json\/wp\/v2\/posts\/452\/revisions\/457"}],"wp:featuredmedia":[{"embeddable":true,"href":"http:\/\/new.guofucourses.cn\/wordpress\/index.php\/wp-json\/wp\/v2\/media\/465"}],"wp:attachment":[{"href":"http:\/\/new.guofucourses.cn\/wordpress\/index.php\/wp-json\/wp\/v2\/media?parent=452"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"http:\/\/new.guofucourses.cn\/wordpress\/index.php\/wp-json\/wp\/v2\/categories?post=452"},{"taxonomy":"post_tag","embeddable":true,"href":"http:\/\/new.guofucourses.cn\/wordpress\/index.php\/wp-json\/wp\/v2\/tags?post=452"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
