Tellurium Element information, properties and uses

Tellurium is present in the Earth''s crust only in about 0.001 parts per million. Tellurium minerals include calaverite, sylvanite and tellurite. It is also found uncombined in nature, but only very rarely. It is obtained commercially from the anode muds produced during the electrolytic refining of copper. These contain up to about 8% tellurium.

Thulium Wikipedia

Thulium is a chemical element with the symbol Tm and atomic number 69. It is the thirteenth and thirdlast element in the lanthanide series. Like the other lanthanides, the most common oxidation state is +3, seen in its oxide, halides and other compounds because it occurs so late in the series, however, the +2 oxidation state is also stabilized by the nearly full 4f shell that results.

In this frequency range, no Raman band could be related to the presence of thallium oxide groups. NMR investigations are ongoing to evaluate the thallium ions environment in these glasses. As the ratio of tellurium oxide to thallium oxide is varied, the ∆ν = 20 THz and ∆ν = 21.3 THz bands vary in terms of strength in the Raman gain curve.
