However, some inevitable factors like light, heat, and moisture affected the stability of CsPbX<sub>3<\/sub>&nbsp;NCs and further limited their practical application. In this work, the stability of all-inorganic halide perovskite NCs can be improved by integrating them in the stable Zr-based metal\u2013organic frameworks (Uio-67). Compared to pristine perovskite NCs, typical CsPbBr<sub>3<\/sub>@Uio-67 composites display a stable photoluminescence property that can be maintained for 30 days under ambient atmospheric conditions. Due to the proposed confinement effects of CsPbX<sub>3<\/sub>&nbsp;NCs coordinated with the pore structures of Uio-67, the related structural model of CsPbX<sub>3<\/sub>@Uio-67 composites was elucidated. White LED device was further fabricated by combining CsPbBr<sub>3<\/sub>@Uio-67 composites and commercial K<sub>2<\/sub>SiF<sub>6<\/sub>:Mn<sup>4+<\/sup>&nbsp;red phosphors with a blue-emitting chip, which demonstrated a wide color gamut (138% of National Television Standards Committee color space). The strategy on encapsulation of CsPbX<sub>3<\/sub>&nbsp;NCs into Uio-67 will open up a stable platform for optoelectronic applications.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>https:\/\/pubs.acs.org\/doi\/abs\/10.1021\/acs.inorgchem.8b03 [&hellip;]<\/p>\n","protected":false},"author":4,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[26],"tags":[79],"class_list":["post-902","post","type-post","status-publish","format-standard","hentry","category-lab_papers_2019","tag-79"],"_links":{"self":[{"href":"http:\/\/ustb.cc\/zh\/wp-json\/wp\/v2\/posts\/902","targetHints":{"allow":["GET"]}}],"collection":[{"href":"http:\/\/ustb.cc\/zh\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"http:\/\/ustb.cc\/zh\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"http:\/\/ustb.cc\/zh\/wp-json\/wp\/v2\/users\/4"}],"replies":[{"embeddable":true,"href":"http:\/\/ustb.cc\/zh\/wp-json\/wp\/v2\/comments?post=902"}],"version-history":[{"count":3,"href":"http:\/\/ustb.cc\/zh\/wp-json\/wp\/v2\/posts\/902\/revisions"}],"predecessor-version":[{"id":2559,"href":"http:\/\/ustb.cc\/zh\/wp-json\/wp\/v2\/posts\/902\/revisions\/2559"}],"wp:attachment":[{"href":"http:\/\/ustb.cc\/zh\/wp-json\/wp\/v2\/media?parent=902"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"http:\/\/ustb.cc\/zh\/wp-json\/wp\/v2\/categories?post=902"},{"taxonomy":"post_tag","embeddable":true,"href":"http:\/\/ustb.cc\/zh\/wp-json\/wp\/v2\/tags?post=902"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
