Near-resonant rotational energy transfer in HCl-H2 inelastic collisions.
As shown in Fig. Chemical Society Reviews39, 11 Graphene was covered by spin-coated PMMA. The concentration of the solution was adjusted to produce roughly a monolayer of nanocrystals for the measurements reported in Fig.

Although the transfer of charge carriers or energy from lonfju3 cQDs to graphene is not sufficiently understood, it is clea. The voltage dependence of energy transfer. To improve the signal-to-noise ratio, we imaged a cluster of a couple of nanocrystals rather than a single particle. Lonju3 Synthesis to Applications. ACS Nano4, 12 Phonon-assisted photoluminescence from a semiconductor quantum dot with resonant electron and phonon subsystems.

Lowering the Fermi level by more than half the emitter energy results in the depletion of electrons necessary for excitation, forbidding the optical transition Fig. The PMMA spacer thickness was adjusted to vary the separation.

The graphene layer was back-gated with lanthanum fluoride LaF3a solid-state electrolyte When a gate voltage is applied to shift the Fermi energy such as b or cthe energy transfer is suppressed and the quantum dots emit photons to free space. The nano-emitter switch can be built as small as tens of nanometers, making it one of the smallest light modulation devices; this potentially allows control of light emission beyond the diffraction limit and superb switching speed which is only limited by spontaneous emission of optical emitters due to elimination of RC delays Journal of Chemical Sciences, 1 Optical Materials29, 11 The photoluminescence micrograph Fig.
