Rare-earth ions

Rare-earth ions are atoms from the lanthanide series located in the periodic table, often used in electronics and lighting. When these ions are incorporated into materials, they can emit specific colors of light or enhance magnetic and conductive properties. Despite their name, they are relatively abundant but tend to be dispersed or difficult to extract. Their unique electronic configurations make them valuable in applications like lasers, phosphors for screens and LEDs, and advanced catalysts, playing a vital role in modern technology.
