A series of synthetic experiments are performed to find an optimal scheme. This phosphor has two emission bands at ~ 545 and ~ 610\u202fnm corresponding to the d-f electronic transition of Ce3+. Large centroid shift of 5d level results in a green light-excitable feature. Compared to other Ce3+-doped nitrides, the crystal field splitting of 5d energy levels for this phosphor, i.e. about 11,300\u202fcm\u22121, is much smaller due to larger volume and smaller distortion of coordination polyhedron of Ce3+. The phosphor shows an excellent luminescent thermal quenching behavior. At 150\u202f\u00b0C, the emission intensity retains about 93% of the initial value at room temperature upon 517\u202fnm excitation. This property can be ascribed to rigid structure and large gap between 5d levels and bottom of conduction band <a href=\"http:\/\/www.east-inflatables.co.nz\/e101019-dinosaur-bouncy-castle.html\" style=\"color: grey; text-decoration: none;\">bouncy castle hamilton nz<\/a>.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Journal of Luminescence 199 (2018) 271\u2013277 Here we repo [&hellip;]<\/p>\n","protected":false},"author":6,"featured_media":0,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"aside","meta":{"footnotes":""},"categories":[25],"tags":[50],"class_list":["post-125","post","type-post","status-publish","format-aside","hentry","category-lab_papers_2018","tag-srlial3n4ce3","post_format-post-format-aside"],"_links":{"self":[{"href":"http:\/\/ustb.cc\/zh\/wp-json\/wp\/v2\/posts\/125","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\/6"}],"replies":[{"embeddable":true,"href":"http:\/\/ustb.cc\/zh\/wp-json\/wp\/v2\/comments?post=125"}],"version-history":[{"count":2,"href":"http:\/\/ustb.cc\/zh\/wp-json\/wp\/v2\/posts\/125\/revisions"}],"predecessor-version":[{"id":3204,"href":"http:\/\/ustb.cc\/zh\/wp-json\/wp\/v2\/posts\/125\/revisions\/3204"}],"wp:attachment":[{"href":"http:\/\/ustb.cc\/zh\/wp-json\/wp\/v2\/media?parent=125"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"http:\/\/ustb.cc\/zh\/wp-json\/wp\/v2\/categories?post=125"},{"taxonomy":"post_tag","embeddable":true,"href":"http:\/\/ustb.cc\/zh\/wp-json\/wp\/v2\/tags?post=125"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
