Thulium selenide is an inorganic compound with the chemical formula Tm₂Se₃. It can be obtained by the reaction of thulium and selenium or thulium oxide and hydrogen selenide at high temperature,[3] or generated in the thermal decomposition of (py)₃Tm(SePh)₃.[2] In the binary system of it and antimony triselenide, TmSb₃Se₆, Tm₆Sb₈Se₂₁, TmSbSe₃ and Tm₈Sb₂Se₁₅ can be formed.[4]
