Abstract
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 Er(3+) dopants.
摘要
开发了一种掺 Er 的 MoS2 层状纳米片的 2D 体系。结构研究表明，Er 原子可以被替代引入 MoS2 中形成稳定的掺杂。密度泛函理论计算表明，该体系保持稳定。在二维过渡金属二卤化物中观察到从近红外到近红外的上转换和下转换发光，归因于来自 Er(3+)掺杂剂的能量跃迁。
