摘　　要：利用简单"一锅煮"的方法快速制备稳定性好、荧光强度高的铕纳米颗粒(Eu NPs@BSA/H2O2)。以氯化铕为铕源、BSA为稳定剂和还原剂,在含有H2O2体系中合成Eu NPs@BSA/H2O2。利用荧光光谱仪考察了合成体系和合成条件对所得纳米颗粒荧光性能的影响。结果表明,反应体系的最佳p H为12. 0,BSA最佳浓度为14. 0 mg m L-1,最佳反应温度为55℃,最佳反应时间为25 min。Eu NPs@BSA/H2O2的粒径分布为2～7nm,其荧光激发和发射峰分别位于～340和～450 nm。In this paper,we developed a simple"one-pot"wet chemical method to synthesize europium nanoparticles( Eu NPs@ BSA/H2 O2) with stabilized and high fluorescence properties.EuNPs@ BSA/H2 O2 weresynthesized by usingeuropium chloride( Eu Cl3) as europium source,bull serum albumin( BSA) as stabilizer and reductant with hydrogen peroxide( H2 O2). In this experiment,fluorescent Eu NPs@ BSA/H2 O2 were synthesized in solvothermal system with14. 0 mg m L-1 BSA( p H = 12. 0) at 55 ℃ for 25 min.The asprepared Eu NPs@ BSA/H2 O2( 2~7 nm diameter) exhibited the excitation and emission peaks at^340 and^450 nm,respectively.
