The LaF3: xmol% Eu3+(x¼1, 3, 5, 8, 10) nanoparticles were prepared by using a modified literature procedure.3In a typical experiment, 0.65 mmol of La2O3and stoichiometric Eu2O3were dissolved in concentrated HNO3firstly by stirring at about 90C, and then 2 ml of methanol was added to form a transparent RE nitrate methanol solution. An aqueous solution of 10.4 mmol of citric acid in 35 ml of deionized water was partially neutralized with 1.5 ml of concentrated NH4OH to a pH of 5.5. 參考文獻:Enhanced emission of ultra-small-sized LaF3:RE3+(RE=Eu, Tb)nanoparticles through 1,2,4,5-benzenetetracarboxylic acid sensitization 文獻地址:http://pubs.rsc.org/en/content/articlehtml/2012/nr/c2nr31206a |
