Barium lithium fluoride nanocrystals less than 100 nm were synthesized in water/ cetyltrimethylammonium bromide ( CTAB)/ 2 octanol microemulsion system and characterized by means of x ray powder diffraction, scanning electron microscopy and infrared spectroscopy. 在水/十六烷基三甲基溴化胺(CTAB)/仲辛醇微乳体系中制备出了粒径小于100nm的BaLiF3纳米晶,用XRD、SEM、IR等手段对产物进行了表征。
