A general, rapid technique is introduced to simultaneously fabricate and functionalize nanoparticles of 2D materials. A femtosecond laser is used to irradiate flakes of 2D materials in an ethanol‐containing solvent. The highly energetic laser pulses exfoliate and cleave the flakes into nanosheets with diameters of ≈3 nm and simultaneously dissociate the solvent molecules. The dissociated carbon and oxygen atoms bond with the freshly cleaved 2D nanoparticles to satisfy edge sites, resulting in the formation of hybrid 2D nanoparticles that contain graphene‐like carbon domains as well as the host material. The technique is demonstrated for molybdenum disulfide (MoS₂), tungsten disulfide (WS₂), and boron nitride (BN) flakes. Notably, the hybrid nanoparticles are formed in as little as 20 min without toxic or corrosive chemicals and are multifunctional. Photoluminescence and absorption owing to both the carbon domains and host 2D material (MoS₂, WS₂, or BN) are observed. This novel hybrid optical behavior makes these materials promising for emerging nanoelectronic and nanophotonic applications.

同时制造和功能化的具有混合光学性质的二维材料的纳米粒子。

引入了一种通用的快速技术来同时制造和功能化2D材料的纳米粒子。飞秒激光用于在含乙醇的溶剂中辐照二维材料的薄片。高能激光脉冲将薄片剥落并切割成直径约≈3nm的纳米片，并同时使溶剂分子解离。解离的碳原子和氧原子与新近裂解的2D纳米粒子结合，以满足边缘位置的需要，从而形成了杂化的2D纳米粒子，其中包含类似石墨烯的碳域以及主体材料。该技术已针对二硫化钼（MoS ₂），二硫化钨（WS ₂）和氮化硼（BN）薄片。值得注意的是，杂化纳米颗粒可在短短20分钟内形成，而没有毒性或腐蚀性化学物质，并且具有多功能性。观察到由于碳域和主体2D材料（MoS ₂，WS ₂或BN）引起的光致发光和吸收。这种新颖的混合光学性能使这些材料有望用于新兴的纳米电子和纳米光子应用。
