MoS/reduced graphene oxide (rGO) nanocomposites were synthesized using an ultrasonic pretreatment with a single-stage hydrothermal and reduction process. Self-assembled MoS layers in the rGO matrix were obtained. The effect of quantum confinement in the structure, controlled by the degree of reduction of graphene oxide and the size of the 2D MoS nanocrystals, made it possible to obtain tunable optical absorption. MoS/rGO layered nanocomposites exhibit a wide UV-IR absorption in the wavelength range from 280 nm to 973 nm, which is attractive for highly efficient multiband solar cells and advanced photonics.
通过单步水热还原过程的超声预处理合成了MoS/还原氧化石墨烯(rGO)纳米复合材料。在rGO基质中获得了自组装的MoS层。通过氧化石墨烯的还原程度和二维MoS纳米晶体的尺寸控制结构中的量子限制效应,使得获得可调谐的光吸收成为可能。MoS/rGO层状纳米复合材料在280nm至973nm波长范围内表现出宽的紫外-红外吸收,这对于高效多波段太阳能电池和先进光子学具有吸引力。
