Thulium sputtering target(Tm)Product overview

Although thulium is relatively rare and expensive, it has some applications in specific fields.

High intensity discharge light source:

Thulium is often introduced into high intensity discharge light sources in the form of high-purity halides (usually thulium bromide) in order to utilize the spectrum of thulium.

Laser:

Ho: Cr: Tm: YAG is a highly efficient active laser medium material. It can emit laser light with a wavelength of 2097 nm, and is widely used in military, medical, and meteorological fields. Thulium monodoped yttrium aluminum garnet (Tm: YAG) can emit laser light with a wavelength between 1930 nm and 2040 nm, which is very effective for ablation of tissue surfaces. It can prevent blood clotting from becoming too deep in both air and water. This makes thulium lasers have great application potential in basic laser surgery.

X-ray source:

Despite the high cost, portable X-ray devices containing thulium are beginning to be widely used as radiation sources in nuclear reactions. These radiation sources have a useful life of about one year, and can be used as medical and dental diagnostic tools, as well as defect detection tools for mechanical and electronic components that are difficult to reach by manpower. These radiation sources do not require significant radiation protection - only a small amount of lead is required.

Thulium 170 is increasingly widely used as a radiation source for cancer brachytherapy. This isotope has a half life of 128.6 days and five emission lines of considerable intensity (7.4, 51.354, 52.389, 59.4, and 84.253 kiloelectron volts). Thulium 170 is also one of the four most commonly used industrial radiation sources.

other:

Similar to yttrium, thulium is also used in high-temperature superconductors. Thulium has potential use in ferrite as a ceramic magnetic material used in microwave equipment. Due to its special spectrum, thulium can be applied to arc lighting like scandium, and the green light emitted by arc lamps using thulium will not be covered by the emission lines of other elements. Due to its ability to emit blue fluorescence under ultraviolet radiation, thulium is also used as one of the anti-counterfeiting marks in euro notes. The blue fluorescence emitted by calcium sulfate added with thulium is used in personal dosimeters for radiation dose testing.

High purity thulium metals have a bright and silver luster. It is fairly stable in the air, but humidity should be avoided. This metal has a soft texture and a Mohs hardness of 2-3, providing plasticity and toughness. Thulium has ferromagnetism below 32K, antiferromagnetism between 32K and 56K, and paramagnetism above 56K. Liquid thulium is highly volatile.

There are two main allotropes of thulium: tetragonal system α- Tm and relatively stable hexagonal crystal system β- Tm。
