Abstract

<abstract abstract-type="main" xml:lang="en"> <title>Abstract</title> <p>A facile strategy to prepare MoS₂–MoO₃ hybrid nanomaterials is developed, based on the heat‐assisted partial oxidation of lithium‐exfoliated MoS₂ nanosheets in air followed by thermal‐annealing‐driven crystallization. The obtained MoS₂–MoO₃ hybrid nanomaterial exhibits p‐type conductivity. As a proof‐of‐concept application, an n‐type SiC/p‐type MoS₂–MoO₃ heterojunction is used as the active layer for light‐emitting diodes. The origins of the electroluminescence from the device are theoretically investigated. This facile synthesis and application of hybrid nanomaterials opens up avenues to develop new advanced materials for various functional applications, such as in electrics, optoelectronics, clean energy, and information storage.</p> </abstract>
