Terbium(III) nitrate is an inorganic chemical compound, a salt of terbium and nitric acid, with the formula {{chem2|Tb(NO3)3}}. The hexahydrate crystallizes as triclinic colorless crystals with the formula {{chem2|[Tb(NO3)3(H2O)4]*2H2O}}. It can be used to synthesize materials with green emission.{{cite journal|last1=Xia|first1=Tifeng|last2=Song|first2=Tao|last3=Zhang|first3=Gege|last4=Cui|first4=Yuanjing|last5=Yang|first5=Yu|last6=Wang|first6=Zhiyu|last7=Qian|first7=Guodong|title=A Terbium Metal-Organic Framework for Highly Selective and Sensitive Luminescence Sensing of Hg2+Ions in Aqueous Solution|journal=Chemistry - A European Journal|volume=22|issue=51|year=2016|pages=18429–18434|issn=0947-6539|doi=10.1002/chem.201603531|pmid=27747951}}
Preparation
Terbium(III) nitrate can be prepared by dissolving terbium(III,IV) oxide in a mixture of aqueous {{chem2|HNO3}} and {{chem2|H2O2}} solution.{{cite journal|last1=Hou|first1=Zhiyao|last2=Wang|first2=Lili|last3=Lian|first3=Hongzhou|last4=Chai|first4=Ruitao|last5=Zhang|first5=Cuimiao|last6=Cheng|first6=Ziyong|last7=Lin|first7=Jun|title=Preparation and luminescence properties of Ce3+ and/or Tb3+ doped LaPO4 nanofibers and microbelts by electrospinning|journal=Journal of Solid State Chemistry|volume=182|issue=4|year=2009|pages=698–708|issn=0022-4596|doi=10.1016/j.jssc.2008.12.021|bibcode=2009JSSCh.182..698H}}
Terbium(III) nitrate can be obtained by reacting terbium(III) oxide with nitric acid and crystallizing then drying the crystals with 45~55% sulfuric acid to obtain the hexahydrate.高胜利, 刘翊纶, 杨祖培.
