Herein, the design and the experimental synthesis of a new family of Mn<sup>2+<\/sup>-doped Cs<sub>2<\/sub>NaBi<sub>1-<\/sub><em><sub>x<\/sub><\/em>In<em><sub>x<\/sub><\/em>Cl<sub>6<\/sub>&nbsp;crystals with an intense orange-yellow emission band are reported, and the phase formation stability is discussed via a combined experimental\u2013theoretical approach. Depending on the manipulation of Bi<sup>3+<\/sup>\/In<sup>3+<\/sup>&nbsp;combination, the band gap increases with In<sup>3+<\/sup>&nbsp;content, and a subsequent evolution from indirect to direct band gap is verified. First-principles calculations and parity analyses indicate a parity forbidden effect on Cs<sub>2<\/sub>NaInCl<sub>6<\/sub>, and a combination effect of absorption on Cs<sub>2<\/sub>NaBi<sub>1-<\/sub><em><sub>x<\/sub><\/em>In<em><sub>x<\/sub><\/em>Cl<sub>6<\/sub>&nbsp;from both Cs<sub>2<\/sub>NaBiCl<sub>6<\/sub>&nbsp;and Cs<sub>2<\/sub>NaInCl<sub>6<\/sub>. The associated Mn<sup>2+<\/sup>-doped photoluminescence depending on the Bi<sup>3+<\/sup>\/In<sup>3+<\/sup>&nbsp;substitution is also addressed from the variation of the different Mn\u2013Cl environment and neighboring-cation effect.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>https:\/\/onlinelibrary.wiley.com\/doi\/abs\/10.1002\/adom.20 [&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":[90],"class_list":["post-912","post","type-post","status-publish","format-standard","hentry","category-lab_papers_2019","tag-mn2"],"_links":{"self":[{"href":"http:\/\/ustb.cc\/zh\/wp-json\/wp\/v2\/posts\/912","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=912"}],"version-history":[{"count":2,"href":"http:\/\/ustb.cc\/zh\/wp-json\/wp\/v2\/posts\/912\/revisions"}],"predecessor-version":[{"id":2556,"href":"http:\/\/ustb.cc\/zh\/wp-json\/wp\/v2\/posts\/912\/revisions\/2556"}],"wp:attachment":[{"href":"http:\/\/ustb.cc\/zh\/wp-json\/wp\/v2\/media?parent=912"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"http:\/\/ustb.cc\/zh\/wp-json\/wp\/v2\/categories?post=912"},{"taxonomy":"post_tag","embeddable":true,"href":"http:\/\/ustb.cc\/zh\/wp-json\/wp\/v2\/tags?post=912"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
