Fluorescence lifetime standards for time and frequency domain fluorescence spectroscopy.
A series of fluorophores with single-exponential fluorescence decays in liquid solution at 20 degrees C were measured independently by nine laboratories using single-photon timing and multifrequency
Ultrafast Dynamics of Photochromic Systems.
Reaction dynamics of the photochromic systems such as spiropyran, flugide and diarylethene derivatives in femto- to nano-second time region was reviewed. The mechanisms of rapid reaction channels in
Rapid optical switching by means of photoinduced change in refractive index of azobenzene liquid crystals detected by reflection-mode analysis
Optical switching behavior of low-molecular-weight and polymer azobenzene liquid crystals (LCs) was explored by means of reflection-mode analysis. Reflectivity changed on pulse irradiation under
Excitation energy transfer in phycobilisomes at −196°C isolated from the cyanobacterium Anabaena variabilis (M-3): evidence for the plural transfer pathways to the terminal emitters
Excitation energy transfer in phycobilisomes at −196°C was studied by means of the time-resolved fluorescence spectroscopy in the picosecond time-range. Supplemental data were obtained from the
Carrier Multiplication in CdTe Quantum Dots by Single-photon Timing Spectroscopy
Carrier multiplication (CM) was observed in CdTe quantum dots (QDs) capped with tetradecylphosphonic acid (TDPA) at hν⁄Eg>2.5 by picosecond single-photon timing spectroscopy, where hν and Eg are th...
Organic chemistry: A digital fluorescent molecular photoswitch
TLDR
This work uses external photostimulation to switch the fluorescence on and off from a single photochromic molecule embedded in a polymer film due to photo-isomerization of the molecule, which may eventually find application in erasable optical data-storage elements.
Chlorophyll-a derivatives with various hydrocarbon ester groups for efficient dye-sensitized solar cells: static and ultrafast evaluations on electron injection and charge collection processes.
Five chlorophyll-a derivatives, chlorins-1-5 possessing C3(2)-carboxy and O17(4)-esterified hydrocarbon groups including methyl, hexyl, dodecyl, 2-butyloctyl, and cholesteryl were synthesized. Their
Excitation energy flow in chlorosome antennas of green photosynthetic bacteria
Energy flow in whole cells of the thermophilic green photosynthetic bacterium Chloroflexus aurantiacus was studied by measurements of time-resolved fluorescence spectra in the picosecond time range,
Plasmonic p-n Junction for Infrared Light to Chemical Energy Conversion.
TLDR
Spectroscopic results revealed that plasmon-induced hot-electron injection at p-n heterojunctions realizes exceptionally long-lived charge separation (>273 μs), which results in efficient IR light to hydrogen conversion, paving the way for the exploration of undeveloped low-energy light for solar fuel generation.
Detection of optical trapping of CdTe quantum dots by two-photon-induced luminescence
Nanometer-sized CdTe quantum dots (QDs) in ${\mathrm{D}}_{2}\mathrm{O}$ can be optically trapped by a high repetition-rate picosecond Nd:YLF laser with an input power as low as
