Robust B-exciton emission at room temperature in few-layers of MoS₂:Ag nanoheterojunctions embedded into a glass matrix.

ABSTRACT: Tailoring the photoluminescence (PL) properties in two-dimensional (2D) molybdenum disulfide (MoS₂) crystals using external factors is critical for its use in valleytronic, nanophotonic and optoelectronic applications. Although significant effort has been devoted towards enhancing or manipulating the excitonic emission in MoS₂ monolayers, the excitonic emission in few-layers MoS₂ has been largely unexplored. Here, we put forward a novel nano-heterojunction system, prepared with a non-lithographic process, to enhance and control such emission. It is based on the incorporation of few-layers MoS₂ into a plasmonic silver metaphosphate glass (AgPO₃) matrix. It is shown that, apart from the enhancement of the emission of both A- and B-excito
