Lutetium is the least abundant element in the lanthanide series. Unlike the other rare earths, it lacks a magnetic moment and also has the smallest metallic radius of any rare earth. Although in limited use due to scarcity, lutetium has been used as a host material for x-ray and LED phosphors, and lutetium aluminium garnet (Al5Lu3O12) has a potential use in highly refractive lenses.Cerium-doped lutetium oxyorthosilicate (LSO) is used in positron emission tomography (PET) detectors.
