Organic/ inorganic hybrid structures have been widely studied because of their enhanced physical and chemical properties. Monolayers of transition metal dichalcogenides (1L-TMDs) and organic nanoparticles can provide a hybridization configuration between zero-and two-dimensional systems with the advantages of convenient preparation and strong interface interaction. Here, we present such a hybrid system made by dispersing p-conjugated organic (tris (8-hydroxyquinoline) aluminum(III)) (Alq(3)) nanoparticles (NPs) on 1L-MoS2. Hybrids of Alq(3) NP/1L-MoS2 exhibited a two-fold increase in the photoluminescence of Alq(3) NPs on 1L-MoS2 and the n-doping effect of 1L-MoS2, and these spectral and electronic modifications were attributed to the charge transfer between Alq(3) NPs and 1L-MoS2. Our results suggested that a hybrid of organic NPs/1L-TMD can offer a convenient platform to study the interface interactions between organic and inorganic nano objects and to engineer optoelectronic devices with enhanced performance.
