“…The enhanced photocurrent may be attributed to the energy transfer from QDs to PSII through Förster resonance energy transfer (FRET). [23][24][25] As mentioned above, smaller amount of PSII could be adsorbed into the pore structure of PAH/CdTe films, which are in close contact with QDs ( Figure S2). The narrow distance and the large overlapped spectra between the emission spectrum of QDs and the absorption spectrum of PSII ( Figure S1) enable the effective FRET from QDs to PSII, thus producing enhanced photocurrent densities.…”

Assembly of CdTe Quantum Dots and Photosystem II Multilayer Films with Enhanced Photocurrent

Photosystem II (PSII) is a photoactive protein that can drive water oxidation under light irradiation. Recently, PSII has been broadly investigated with the high demand on the bioenergy. Here, we demonstrate a facile approach for the fabrication of a photoactive electrode by the integration of PSII with quantum dots (QDs)/polyelectrolyte multilayers. The assembled QDs and PSII film with a polyelectrolyte based substrate via layer-by-layer assembly can remain the photoactivity of the PSII and broaden the absorption spectrum of PSII to produce a high photocurrent yield. The co-assembly exhibits an obviously enhanced photocurrent under UV light irradiation. The proposed strategy can be considered for the reference and usage of PSII toward the solar energy conversion.

“…Compared to that of CdSe QDs, the emission spectrum of CdTe QDs possesses larger overlaps with PSII's absorption spectrum, especially at the "red" region. [23][24][25] Nevertheless, the possible energy transfer between CdTe QDs and PSII and the potential application of QDs in PSII based PEC cells have been rarely explored.…”

“…From the image method [20], we learn that in the presence of a metallic interface, the electric field above it can be calculated as a sum of radiation patterns of two dipoles -primary and imaginary , where (5) Keeping in mind that the position and orientation of the imaginary dipole is determined by mirror image of the primary dipole, one can calculate the plasmon-assisted interaction energy as a sum of two dipole-dipole interaction formulas.…”

“…The efficiency of both processes can be improved through coupling with metallic and semiconducting nanoparticles [1]. Plasmon excitations in MNPs [2] enhance absorption of light in light-harvesting complexes [3,4], while attachement of semiconducting nanocrystals could result in expanding the spectral range of absorption [5]. Furthermore, plasmon excitations have been shown to influence the energy transfer between a donor and acceptor in artificially constructed molecular assemblies [6,7].…”

In this work we investigate theoretically the effects imposed by plasmon excitations in spherical metallic nanoparticles (MNPs) on the rate of energy transfer in peridinin-chlorophyllprotein (PCP) complex reconstituted with both chlorophyll a (Chl a) and chlorophyll b (Chl b). This light-harvesting complex is unique since it features efficient energy transfer both from higher-lying Chl b to lower-lying Chl a as well as in the opposite, less energy-favorable direction. The results of calculations show that the Förster energy transfer rate decreases with a MNP-PCP distance changing from to , while the energy transfer from Chl a to Chl b remains less efficient at all distances. We conclude that plasmon excitations allow for controlling the energy transfer between Chls, as well as the excitation distribution between two spectrally distinguishable Chls within the reconstituted PCP complex.

“…Engineering surfaces of inorganic nanomaterials with functional dyes provides the ability to independently tune the energy levels of each component, and thus will pave the way for the development of new photonic devices with finely-tuned optoelectronic properties [9,10]. On the basis of the idea that the rapidly emerging field of the plasmonics can be applied to construction of not only superior photonic devices based on surface electromagnetic field enhancement [11,12], but also efficient solar energy conversion systems [13], considerable effort has been devoted to develop efficient synthetic routes for the generation of organic-inorganic hybrid nanomaterials [14][15][16].…”

Detailed exploratory and mechanistic investigations on spontaneous formation of dye-functionalized gold nanoparticles (GNPs) using dye-based reverse micellar systems are described in this publication. The accumulated results from spectroscopic and microscopic investigations demonstrated that water molecules confined within nanoscopic enclosure of the self-assembled reverse micelles played critical role in the redox processes of aurate ions to produce GNPs, which are assumed to have approximately constant size distributions. The resulting dye-functionalized GNPs were found to offer their absorption and fluorescence emission tunability by changing the medium polarity as well as to exhibit excellent film-forming properties to give optically homogeneous polystyrene thin films. These key findings in addition to broad applicability of the self-assembling process with a variety of dye analogues have led to a conclusion that the protocol presented here serves as a versatile synthetic method to provide a potential convenience for future development of new organic-inorganic hybrid nanomaterials.
