Rare earth sulfides are composed of rare earth elements (cerium (Ce), europium (Eu), lanthanum (La), neodymium (Nd), praseodymium (Pr), ytterbium (Yb), gadolinium (Gd), holmium (Ho), ytterbium ( Yb), thulium (Tm), scandium (Sc), terbium (Tb), samarium (Sm), lutetium (Lu), erbium (Er) and dysprosium (Dy)) and sulfur compounds. Rare earth sulfides have more complex structures. Rare earth sesquisulfides RE2S3 (RE is a rare earth element, the same below) have various crystal structures such as orthorhombic, tetragonal, cubic, and monoclinic, and ternary and multicomponent rare earth sulfides have more complex structures. for abundance. Rare earth sulfides are a new class of functionalized materials with complex crystal structures and unique advantages in electrical, optical and magnetic properties. Rare earth sulfides are widely used in the fields of pigments, new energy materials and catalysis, and have broad development prospects. They are research hotspots in recent years.
