nm附近,并有微量Li2Ca<span style=\"color:red\">3</span>Si6O16新物质生成.研究结果还表明,Li+的加入降低了样品的合成温度.当不加Li+时,最佳焙烧温度为1 200 ℃;加入Li+质量分数为0.15%时,最佳焙烧温度为1 100 ℃;当Li+质量分数增加到0.65%时,最佳焙烧温度降至900 ℃.SEM分析表明,随着Li+的加入,样品逐渐由三维网络块状结构变为不规则形状,且荧光粉颗粒粒径逐渐减小.","authors":[{"authorName":"杨良准","id":"d26f47ad-314d-44be-ae19-80e3974ea2d6","originalAuthorName":"杨良准"},{"authorName":"方敏","id":"9a0ae202-bbe3-4396-8444-144498e27423","originalAuthorName":"方敏"},{"authorName":"杜立芬","id":"8e7e0d7a-9611-42ac-9980-abd61f0b01a8","originalAuthorName":"杜立芬"},{"authorName":"刘洁","id":"f79f4e34-4e4b-46d4-bbc3-128891796ac6","originalAuthorName":"刘洁"},{"authorName":"沈新峰","id":"04c57926-ef4a-47a7-a0bc-5851a189051b","originalAuthorName":"沈新峰"},{"authorName":"张兰芬","id":"35d148e4-0a92-4899-ba59-e45a371ae63c","originalAuthorName":"张兰芬"},{"authorName":"余锡宾","id":"003d33da-38a6-46b8-9723-5d7436c48e48","originalAuthorName":"余锡宾"}],"doi":"10.3969/j.issn.1000-0518.2007.05.017","fpage":"565","id":"cf473913-fcb2-4ddd-9505-69766072c8aa","issue":"5","journal":{"abbrevTitle":"YYHX","coverImgSrc":"journal/img/cover/YYHX.jpg","id":"73","issnPpub":"1000-0518","publisherId":"YYHX","title":"应用化学"},"keywords":[{"id":"135691b3-48bc-42cc-bcbe-0cdb6ffcd822","keyword":"Li+掺杂","originalKeyword":"Li+掺杂"},{"id":"956add23-821c-48cb-acf3-e88026a3887e","keyword":"偏硅酸盐","originalKeyword":"偏硅酸盐"},{"id":"e44d8dec-02dc-43c5-8d7e-de353cff8dd8","keyword":"晶体结构","originalKeyword":"晶体结构"},{"id":"0da3acbf-3db7-4be6-8800-a018bbb0ed76","keyword":"荧光性能","originalKeyword":"荧光性能"}],"language":"zh","publisherId":"yyhx200705017","title":"Li+掺杂对<span
