Thulium (III) oxide is a pale green solid compound, with the formula Tm2O3. It was first isolated in 1878 from an impure sample of erbia by Per Teodor Cleve, who named it thulia. It can be prepared in the laboratory by burning thulium metal in air, or by decomposition of their oxoacid salts, such as thulium nitrate. [1]


Thulium is a chemical element with symbol Tm and atomic number 69. It is the thirteenth and antepenultimate (third-last) element in the lanthanide series. Like the other lanthanides, the most common oxidation state is +3, seen in its oxide, halides and other compounds. In aqueous solution, like compounds of other late lanthanides, soluble thulium compounds form complexes with nine water molecules.

In 1879, Swedish chemist Per Theodor Cleve separated in the rare earth erbia another two previously unknown components, which he called holmia and thulia: these were the oxides of holmium and thulium respectively. A relatively pure sample of thulium metal was first obtained in 1911.
Thulium is the second least abundant of the lanthanides after promethium, which is only found in trace quantities on Earth. It is an easily workable metal with a bright silvery-gray luster. It is fairly soft and slowly tarnishes in air. Despite its high price and rarity, thulium is used as the radiation source in portable X-ray devices and in solid-state lasers. It has no significant biological role and is not particularly toxic
