Source:Phys.OrgModern technology depends on a set of 17 elements at the foot of the periodic table. Known as rare earths (REs), many of these metals are highly magnetic, and find use in computing, green power and other technologies. However, because of rising prices, legal issues and the difficulty of mining, safeguarding their supply is a major scientific and political challenge.Several REs, such as yttrium (Y) and europium (Eu), are used as phosphors in fluorescent lamps (FLs). These lamps increasingly replace traditional incandescent lighting, but have a limited lifespan. End-of-life FLs ar...
