摘要
用Ｓｏｌ－Ｇｅｌ法和微波法合成了亚纳米级Ｚｎ２ＳｉＯ４∶Ｍｎ２＋ ， Ｅｒ３＋ 高效绿色荧光体， 考察了Ｍｎ２＋ 单掺和Ｅｒ３＋ 敏化的荧光体的发光， 探讨了掺杂浓度对发光性质的影响， 发现Ｅｒ３＋ 可有效敏化Ｍｎ２＋ 的发光． ＳＥＭ 表明Ｚｎ２ＳｉＯ４∶Ｍｎ２＋ ， Ｅｒ３＋ 的粒度约为１５０～３５０ｎｍ ．
In this paper, Sol Gel method and microwave radiation method were used to synthesize the phosphors of silicate oxyapatites doped with Mn 2+ , or codoped with Mn 2+ and Er 3+ . The high efficient, green color, subnanometer phosphors of Zn 2SiO 4∶Mn 2+ , Er 3+ , with 150～350nm were obtained by means of these two methods.
