Production

It can be produced by reacting thulium(III) sulfide and hydrofluoric acid, followed by thermal decomposition:¹

Thulium(III) oxide reacts with fluorinating agents such as hydrogen fluoride,² nitrogen trifluoride³ xenon difluoride⁴ to create thullium(III) fluoride as well, although the reaction with nitrogen trifluoride is incomplete and produces a mixture of TmOF and TmF3.⁵
