摘要

Abstract

Mid-infrared (MIR) light-emitting device

s play a key role in optical communications

thermal imaging

and material analysis applications. Two-dimensional (2D) materials offer a promising direction for next-generation MIR devices owing to their exotic optical properties

as well as the ultimate thickness limit. More importantly

van der Waals heterostructures—combining the best of various 2D materials at an artificial atomic level—provide many new possibilities for constructing MIR light-emitting devices of large tuneability and high integration. Here

we introduce a simple but novel van der Waals heterostructure for MIR light-emission applications built from thin-film BP and transition metal dichalcogenides (TMDCs)

in which BP acts as an MIR light-emission layer. For BP–WSe

heterostructures

an enhancement of ~200% in the photoluminescence intensities in the MIR region is observed

demonstrating highly efficient energy transfer in this heterostructure with type-Ⅰ band alignment. For BP–MoS

heterostructures

a room temperature MIR light-emitting diode (LED) is enabled through the formation of a vertical PN heterojunction at the interface. Our work reveals that the BP–TMDC heterostructure with efficient light emission in the MIR range

either optically or electrically activated

provides a promising platform for infrared light property studies and applications.
