An Entity of Type: Thing, from Named Graph: http://dbpedia.org, within Data Space: dbpedia.org

Terbium compounds are compounds formed by the lanthanide metal terbium (Tb). Terbium generally exhibits the +3 oxidation state in these compounds, such as in TbCl3, Tb(NO3)3 and Tb(CH3COO)3. Compounds with terbium in the +4 oxidation state are also known, such as TbO2 and BaTbF6. Terbium can also form compounds in the 0, +1 and +2 oxidation states.

  • Terbium compounds are compounds formed by the lanthanide metal terbium (Tb). Terbium generally exhibits the +3 oxidation state in these compounds, such as in TbCl3, Tb(NO3)3 and Tb(CH3COO)3. Compounds with terbium in the +4 oxidation state are also known, such as TbO2 and BaTbF6. Terbium can also form compounds in the 0, +1 and +2 oxidation states. The trivalent terbium ion is generally colorless in aqueous solution, and when it is irradiated by certain wavelengths of ultraviolet light (such as 254 nm or 365 nm) in solution or crystal form, it will emit green fluorescence. This property has given rise to applications in fields such as optics. (en)
  • 铽化合物是镧系金属铽（元素符号：Tb）形成的化合物，在这些化合物中，铽一般显+3价，如TbCl3、Tb(NO3)3等；+4价的铽化合物如TbO2、BaTbF6也是已知的。 三价铽离子在水溶液中一般是无色的，它在溶液或晶体中被一定波长的紫外光（如254 nm或365 nm）照射时，会发出绿色的荧光。这一性质产生了光学等领域的应用。 (zh)
