Thulium (Tm) Nanoparticles - Properties, Applications

Nanoparticles are being used across several high-tech industries due to their excellent catalytic, magnetic and optical properties. The properties of nanoparticles depend on their size, shape and structure.

Thulium is an easily workable metal that slowly tarnishes in air and reacts with water. It emits blue color upon excitation in flat panel screens, and UV and visible light under X-ray bombardment, which makes it useful for low radiation detection for detection badges.

Thulium nanoparticles have useful magnetic and optical properties.
