开发了掺铒 MoS2 层状纳米片的二维系统。结构研究表明Er原子可以置换引入MoS2中形成稳定的掺杂。密度泛函理论计算表明系统保持稳定。在二维过渡金属二硫属化物中观察到近红外到近红外上转换和下转换发光，这归因于 Er3+ 掺杂剂的能量跃迁。
A 2D system of Er-doped MoS2 layered nanosheets is developed. Structural studies indicate that the Er atoms can be substitutionally introduced into MoS2 to form stable doping. Density functional theory calculation implies that the system remains stable. Both NIR-to-NIR up-conversion and down-conversion light-emissions are observed in 2D transition metal dichalcogenides, ascribed to the energy transition from Er3+ dopants.
