In this paper, we have synthesized a series of Sr2-2xEu2xSi5N8\u00a0(0\u202f\u2264\u202fx\u202f\u2264\u202f1) solid-solution compounds, and have systemically investigated effects of full-range Eu concentration on their\u00a0luminescence. Their emission band maximum can be largely tuned from 610 to 725\u202fnm by increasing Eu content. Reabsorption at low Eu2+\u00a0concentration while both the energy transfer and Stocks shift at high Eu2+\u00a0concentration account for this large spectral red-shift. Luminescent thermal quenching performance gets worse with Eu2+\u00a0concentration increasing. The compound with x\u202f=\u202f0.15 possesses the best crystallinity and the highest luminescence intensity with the peak position around 660\u202fnm, and still maintains 88.5% room-temperature intensity at 400\u202fK, indicating that great potential for the application as a deep-red phosphor <a href='https:\/\/www.east-hinchable.es\/e108002-tiendas-de-campana-hinchables.html' style=\"color: grey; text-decoration: none;\">tienda de campa\u00f1a hinchable<\/a>.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Journal of Alloys and Compounds, Volume 770,\u00a05 January  [&hellip;]<\/p>\n","protected":false},"author":4,"featured_media":0,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"aside","meta":{"footnotes":""},"categories":[26],"tags":[35,80,82],"class_list":["post-148","post","type-post","status-publish","format-aside","hentry","category-lab_papers_2019","tag-ce3","tag-80","tag-82","post_format-post-format-aside"],"_links":{"self":[{"href":"http:\/\/ustb.cc\/zh\/wp-json\/wp\/v2\/posts\/148","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=148"}],"version-history":[{"count":2,"href":"http:\/\/ustb.cc\/zh\/wp-json\/wp\/v2\/posts\/148\/revisions"}],"predecessor-version":[{"id":3195,"href":"http:\/\/ustb.cc\/zh\/wp-json\/wp\/v2\/posts\/148\/revisions\/3195"}],"wp:attachment":[{"href":"http:\/\/ustb.cc\/zh\/wp-json\/wp\/v2\/media?parent=148"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"http:\/\/ustb.cc\/zh\/wp-json\/wp\/v2\/categories?post=148"},{"taxonomy":"post_tag","embeddable":true,"href":"http:\/\/ustb.cc\/zh\/wp-json\/wp\/v2\/tags?post=148"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
