Terbium compounds

The terbium compounds are excited by UV light at 365 nm and emits green light.

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.^[1] Terbium can also form compounds in the 0,^[2]^[3] +1^[4] and +2 oxidation states.

The trivalent terbium ion (Tb³⁺) 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.^[5] The tetravalent terbium ion (Tb⁴⁺) is non-luminescent and its coexistence with Tb³⁺ will reduce the green emission of Tb³⁺.^[6]
