| 摘 要： | BaLiF3属立方钙钛矿型复合氟化物, 作为高效闪烁晶体可用于热中子检测［1］. 由于其能带隙宽, 易于实现各种不同价态稀土离子掺杂, 可以获得许多可调谐性质, 因此它也是比较理想的光学功能材料的基质［2］. Ce3+激活的BaLiF3晶体作为紫外发射的短波固体激光材料和光放大材料的研究多有报道［3~5］

| Abstract: | Abstract The complex fluoride BaLiF3 and BaLiF3∶Ce3+ nanocrystals were synthesized in cetyltrimethylammonium bromide(CTAB)/2 octanol/water microemulsion systems. XRD analysis shows that the products were single phase and XPS analysis shows the oxygen content was low. The result of ESEM confirms that the average size of the BaLiF3 nanocrystals was 28 nm in diameter. The emission peak of the BaLiF3∶Ce3+ nano-particles synthesized by microemulsion shows obvious blue shift in comparison with that of BaLiF3∶Ce3+ synthesized by the reaction at a high temperature and full width at half maximum(FWHM) of emission band was broaden. |
