Title: Lifetime and linewidth of individual quantum dots interfaced with graphene

Abstract

Here, we report on luminescence lifetimes and linewidths from an array of individual quantum dots (QDs) that were either interfaced with graphene surface guides or dispersed on aluminum electrodes. The observed fluorescence quenching is consistent with screening by charge carriers. Fluorescence quenching is typically mentioned as a sign that chromophores are interfacing with a conductive surface (metal or graphene); we find that the QDs interfaced with the metal film exhibit shortened lifetime and line-broadening but not necessarily fluorescence quenching as the latter may be impacted by molecular concentration, reflectivity and conductor imperfections. We also comment on angle-dependent lifetime measurements, which we postulate depend on the specifics of the local density-of-states involved.

The Effect of Periodic Spatial Perturbations on the Emission Rates of Quantum Dots near Graphene Platforms

Journal Article Miao, Xin ; Gosztola, David J. ; Ma, Xuedan ; ... - Materials

The quenching of fluorescence (FL) at the vicinity of conductive surfaces and, in particular, near a 2-D graphene layer has become an important biochemical sensing tool. The quenching is attributed to fast non-radiative energy transfer between a chromophore (here, a Quantum Dot, QD) and the lossy graphene layer. Increased emission rate is also observed when the QD is coupled to a resonator. Here, we combine the two effects in order to control the emission lifetime of the QD. In our case, the resonator was defined by an array of nano-holes in the oxide substrate underneath a graphene surface guide. Atmore »« less

Inhomogeneous linewidth broadening and radiative lifetime dispersion of size dependent direct bandgap radiation in Si quantum dot

Journal Article Wu, Chung-Lun ; Lin, Gong-Ru - AIP Advances

The SiO{sub x} (SiO{sub x}:Si-QDs) with buried Si quantum dots (Si-QDs) is synthesized by plasma-enhanced chemical vapor deposition (PECVD), and the size-dependent wave-function of Si-QDs embedded in Si-rich SiO{sub 2} matrix is experimentally and theoretically analyzed to reformulate its bandgap energy as E{sub g}(d) = 1.12+5.83/d{sup 1.78}. The photoluminescent lifetime of Si-QDs is dominated by the non-phonon assisted radiative recombination. Shrinking the Si-QD size from 4.3 to 1.9 nm increases the overlapping probability of electron-hole wave-functions in Si-QD to shorten the non-phonon assisted radiative lifetime from 6.3 {mu}s to 83 ns.

Role of Atomic Structure on Exciton Dynamics and Photoluminescence in NIR Emissive InAs/InP/ZnSe Quantum Dots

Journal Article Enright, Michael J. ; Jasrasaria, Dipti ; Hanchard, Mathilde M. ; ... - Journal of Physical Chemistry. C

The development of bright, near-infrared-emissive quantum dots (QDs) is a necessary requirement for the realization of important new classes of technology. Specifically, there exist significant needs for brighter, heavy metal-free, near-infrared (NIR) QDs for applications with high radiative efficiency that span diverse applications, including down-conversion emitters for high-performance luminescent solar concentrators. In this work, we use a combination of theoretical and experimental approaches to synthesize bright, NIR luminescent InAs/InP/ZnSe QDs and elucidate fundamental material attributes that remain obstacles for development of near-unity NIR QD luminophores. First, using Monte Carlo ray tracing, we identify the atomic and electronic structural attributes ofmore »« less

Fluorescence quenching of CdSe quantum dots on graphene

Journal Article Guo, Xi Tao ; Hua Ni, Zhen, E-mail: zhni@seu.edu.cn ; Yan Nan, Hai ; ... - Applied Physics Letters

We studied systematically the fluorescence quenching of CdSe quantum dots (QDs) on graphene and its multilayers, as well as graphene oxide (GO) and reduced graphene oxide (rGO). Raman intensity of QDs was used as a quantitatively measurement of its concentration in order to achieve a reliable quenching factor (QF). It was found that the QF of graphene (∼13.1) and its multilayers is much larger than rGO (∼4.4), while GO (∼1.5) has the lowest quenching efficiency, which suggests that the graphitic structure is an important factor for quenching the fluorescence of QDs. It was also revealed that the QF of graphenemore »« less

Effect of MgO shell on electron transfer from Cu doped ZnInS quantum dots to FePt nanoparticles

Journal Article Liu, Yang ; Hua, Jie ; Zhang, Kewei ; ... - Materials Research Bulletin

Highlights: • MgO-coated FePt NPs were synthesized using 4 nm FePt cores as seeds for the growth of MgO shell. • Significant PL quenching took place in Cu doped ZnInS QD-FePt NP system owing to photoexcited electron transfer. • The formation of interfacial MgO barriers could efficiently restrain the electron transfer at QD-FePt interface. - Abstract: The effect of MgO shell on the electron transfer between luminescent Cu doped ZnInS quantum dots (QDs) and magnetic FePt/MgO core/shell nanoparticles (NPs) was studied by using steady-state and time-resolved photoluminescence (PL) spectroscopy. MgO-coated FePt NPs were synthesized using 4 nm FePt cores asmore »« less
