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，鈰、鋱共激活鋁酸鍶基光致發光粉體發光效果比較好；將tb _ 4o _ 7 、 srco _ 3和a1 _ 2o _ 3為原料，在適當的條件下可以合成在235nm或365nm紫外光激發下發出較強綠光的sral _ 2o _ 4 ： （ tb ）發光粉；加入ceo _ 2合成sral _ 2o _ 4 ： （ ce ， tb ）可以增強sral _ 2o _ 4發光粉體的發光性能：在合咸溫度下保溫時間對合成樣品的發光效果有重要影響；隨實驗條件的改變可以制備出發紅、黃、綠色光的磷光體；通過x射線物相分析法對合成物的物相組成進行測定。
