“…Graphene, in particular, has been extensively utilized as an acceptor material in FRET processes involving several donor systems: dye molecules, , quantum dots, diamond nitrogen-vacancy (NV) centers, , rare-earth elements, and hexagonal boron nitride (hBN) emitters . The same can be said for TMDs, which have been used both as acceptor materials for quantum dots, NV centers, and hBN emitters, as well as donor materials coupled to graphene . Here, we review a selection of studies which focus on energy and/or charge transfer mechanisms involving two-dimensional, van der Waals materials.…”

Energy and charge transfer processes in interacting donor−acceptor systems are the bedrock of many fundamental studies and technological applications ranging from biosensing to energy storage and quantum optoelectronics. Central to the understanding and utilization of these transfer processes is having full control over the donor−acceptor distance. With their atomic thickness and ease of integrability, two-dimensional materials are naturally emerging as an ideal platform for the task. Here, we review how van der Waals semiconductors are shaping the field. We present a selection of some of the most significant demonstrations involving transfer processes in layered materials that deepen our understanding of transfer dynamics and are leading to intriguing practical realizations. Alongside current achievements, we discuss outstanding challenges and future opportunities.

The quantum optical phenomena, such as single photon emission, in two-dimensional (2D) transition metal dichalcogenides (TMDCs) have triggered extensive researches on 2D material-based quantum optics and devices. By far, most reported quantum optical emissions in TMDCs are based on atomic defects in the material or the local confinement of excitons by introducing local stain or potential. In contrast, energy transfer between two materials could also manipulate the photon emission behaviors in materials, even at the single photon level. Along with the single-photon emission nature of zero-dimensional (0D) quantum dots (QDs) at room temperature, constructing a 0D-2D hybrid heterostructure may provide an effective way to regulate the quantum states related optical emissions of TMDCs. Here, we report on fluorescence blinking, a quantum phenomenon, from MoS2 atomic layers in QD/ MoS2 heterostructure at room temperature. We demonstrate the single-photon nature of the QDs in heterostructures by second-order photon correlation measurements. Based on the transient PL spectroscopy and PL time trajectories, we attribute the fluorescence blinking behavior in MoS2 to the single photon energy transfer from QD to MoS2. Our work opens the possibility to achieve correlated quantum emitters in TMDCs at room temperature by controlling the energy transfer between QD and TMDCs.

The quantum optical phenomena, such as single-photon emission, in transition metal dichalcogenides (TMDCs) have triggered extensive research on 2D material-based quantum optics and devices. By far, most reported quantum optical emissions in TMDCs are based on atomic defects or the local confinement of excitons. In contrast, energy transfer between two materials could also manipulate the photon emission behaviors in materials, even at the single-photon level. Here, fluorescence blinking from MoS 2 atomic layers in quantum dot (QD)/MoS 2 hybrid heterostructure at room temperature is reported. The single-photon nature of the QDs in heterostructures by second-order photon correlation measurements is demonstrated. Based on the transient PL spectroscopy and PL time trajectories, the fluorescence blinking behavior in MoS 2 is attributed to the single-photon energy transfer from QD to MoS 2 . This work could open the possibility to achieve correlated quantum emitters in TMDCs at room temperature.
