“…In addition, Figure 2C2 shows bare GO suspension of the same concentration. Since the distance between the QDs and GO is very crucial for non-radiative energy transfer between them as Lin et al (2013) recorded that quenching is not strongly observable at distances greater than 20 nm, so here the target bacteria (≈ 0.5×2 µm size) acts as a spacer between the donor and the acceptor hindering the photons transfer and keeping the fluorescence of QDs. Figure 2D shows a SEM micrograph of QDs-Ab conjugates are capturing to bacterial cells of E coli O157:H7.…”

“…If the sample does not have E. coli O157:H7, the test line will be efficiently quenched when adding GO by FRET, since the distance between QDs/Abs (donor) and GO (acceptor) is few nanometres (Gaudreau, Tielrooij, Prawiroatmodjo, Osmond, de Abajo, andKoppens, 2013, Lin et al, 2013). On the other hand, if the sample has E. coli O157:H7, it will be selectively captured by the specific QDs/Abs probe on the test line, then after adding GO, resonance energy transfer is hindered or minimally occurs since the distance between GO and QDs exceeds to more than 20 nm by the bacteria interference (Gaudreau et al, 2013, Lin et al, 2013.…”

“…In the case of colloidal quantum well donors, a slight deviation from d −4 scaling was observed at short distances, which has been attributed to the larger lateral extent of the free excitons in the nanoplatelets, leading to a deviation from classical dipole emitter approximation . Few studies reported different distance dependencies such as d −2.5 and d −2 . However, these unexpected scaling terms could simply arise due to the unexpected experimental conditions (e.g., non‐smooth spacer layers) or potential charge transfer pathways.…”

wileyonlinelibrary.comtelecommunications. Conventional optoelectronics relies on high-temperature, gas-phase, epitaxy-grown semiconductors such as III-V compounds, [1,2] which make a mature materials technology. However, high-thermal budget, high-cost, and a limited set of substrates, which are CMOS-incompatible, hamper their use in versatile platforms, including flexible surfaces and large-area applications. Besides, the last decade has witnessed the rise of alternative low-dimensional semiconductor materials such as colloidal semiconductor nanocrystals, [3] organic semiconductors [4,5] and more recently, two-dimensional (2D) semiconductors. [6] These materials offer advantages over conventional semiconductors thanks to their low cost and low thermal budget growth, solution processability, and roll-to-roll fabrication on arbitrary substrates on a large scale. These materials are expected to impact a broad range of applications in optoelectronics and electronics.In bulk and weakly confined semiconductors, the excited electronic state is typically in the form of free electron-hole pairs due to weak Coulomb interaction energy (∼10 meV). [7] On the other hand, in low-dimensional nanoemitters, the excited state is essentially in the form of strongly bound electron-hole pairs (i.e., excitons) with large Coulomb interaction energy (10 meV) thanks to strong quantum confinement [8] and large dielectric screening, [9,10] allowing for strong light-matter interactions. Thus, in these nanoemitters, it becomes central to control excitonic interactions including exciton transfer, diffusion, trapping, dissociation, annihilation, and radiative recombination to accomplish the desired photonic properties and maximize optoelectronic performance.As it naturally happens in photosynthetic light-harvesting complexes, efficient and directed exciton flow is highly desired in semiconductor nanostructures. To this end, mastering exciton flow at the nanoscale through near-field nonradiative energy transfer has proven vital to accomplish efficient light generation and light utilization using nanoemitters and their hybrid nanostructures. [7,[11][12][13][14][15] In this feature article, we highlight recent developments in the field of energy transfer materials for optoelectronics. We review new insights on the near-field nonradiative transfer in excitonic nanoemitter systems. Our main focus is on hybrid systems comprising colloidal nanocrystals, and 2D and organic semiconductors. Also, Effective utilization of excitation energy in nanoemitters requires control of exciton flow at the nanoscale. This can be readily achieved by exploiting nearfield nonradiative energy transfer mechanisms such as dipole-dipole coupling (i.e., Förster resonance energy transfer) and simultaneous two-way electron transfer via exchange interaction (i.e., Dexter energy transfer). In this feature article, we review nonradiative energy transfer processes between emerging nanoemitters and exciton scavengers. To this end, we highlight the potential of colloidal semiconduct...

“…Interestingly, in studies in which GO was used as the acceptor, quenching was observable at distances greater than 20 nm. [14] Graphene oxide has been reported to be a universal highly efficient long-range quencher of fluorescence. [7] Our group previously reported the extraordinary performance of GO as a quencher of QD fluorescence emission in the solid phase.…”
