| 1. | In the process of study , by a lot of experiments for analyzing luminescent properties " affecting factors , such as concentration ce and tb h3bo : i , synthesizing temperature and temperature reserving time , reducing condition , etc , it gives out a good foundation for synthesizing ideal rare earths luminescent materials activated by ce and tb in aluminates strontium host . the study indicated that photoluminesent aluminates strontium power activated by ce , tb , in sral . , 0 , , has a better luminescent effect . under the appropriate condition , srall . 0 ( that produce olivine light can be composed in 235nm or 365nm ul traviolet radiat ion act i vated by tbi07 , al , > 0 . i and srco : !
研究表明，铈、铽共激活铝酸锶基光致发光粉体发光效果比较好；将tb _ 4o _ 7 、 srco _ 3和a1 _ 2o _ 3为原料，在适当的条件下可以合成在235nm或365nm紫外光激发下发出较强绿光的sral _ 2o _ 4 ： ( tb )发光粉；加入ceo _ 2合成sral _ 2o _ 4 ： ( ce ， tb )可以增强sral _ 2o _ 4发光粉体的发光性能：在合咸温度下保温时间对合成样品的发光效果有重要影响；随实验条件的改变可以制备出发红、黄、绿色光的磷光体；通过x射线物相分析法对合成物的物相组成进行测定。 |
