Herein, we have synthesized a garnet-type Ca3Y2Ge3O12:Cr3+&nbsp;NIR phosphor using solid state reaction method. Broadband NIR emission ranging from 700 to 1100&nbsp;nm with a peak located at 800&nbsp;nm indicates a weak crystal field strength for Cr3+, which occupies the six-coordinated Y3+&nbsp;site. Moreover, the phosphor has satisfactory luminous intensity showing 81%\/10% internal\/external quantum efficiency and excellent luminescence thermal stability. Our work provides an excellent NIR phosphor choice for NIR LED devices.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Journal of Alloys and Compounds, Volume 863, 15 May 202 [&hellip;]<\/p>\n","protected":false},"author":4,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[28,7],"tags":[36,44],"class_list":["post-274","post","type-post","status-publish","format-standard","hentry","category-lab_papers_2021","category-recommend","tag-cr3","tag-nir"],"_links":{"self":[{"href":"http:\/\/ustb.cc\/zh\/wp-json\/wp\/v2\/posts\/274","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=274"}],"version-history":[{"count":1,"href":"http:\/\/ustb.cc\/zh\/wp-json\/wp\/v2\/posts\/274\/revisions"}],"predecessor-version":[{"id":2518,"href":"http:\/\/ustb.cc\/zh\/wp-json\/wp\/v2\/posts\/274\/revisions\/2518"}],"wp:attachment":[{"href":"http:\/\/ustb.cc\/zh\/wp-json\/wp\/v2\/media?parent=274"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"http:\/\/ustb.cc\/zh\/wp-json\/wp\/v2\/categories?post=274"},{"taxonomy":"post_tag","embeddable":true,"href":"http:\/\/ustb.cc\/zh\/wp-json\/wp\/v2\/tags?post=274"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
