Nearly 100% internal phosphorescence efficiency in an organic light emitting device
We demonstrate very high efficiency electrophosphorescence in organic light-emitting devices employing a phosphorescent molecule doped into a wide energy gap host. Using
Highly efficient phosphorescent emission from organic electroluminescent devices
The efficiency of electroluminescent organic light-emitting devices, can be improved by the introduction of a fluorescent dye. Energy transfer from the host to the dye occurs via excitons, but only
VERY HIGH-EFFICIENCY GREEN ORGANIC LIGHT-EMITTING DEVICES BASED ON ELECTROPHOSPHORESCENCE
We describe the performance of an organic light-emitting device employing the green electrophosphorescent material, fac tris(2-phenylpyridine) iridium [Ir(ppy)3] doped into a
High-Efficiency Organic Solar Concentrators for Photovoltaics
TLDR
The exploitation of near-field energy transfer, solid-state solvation, and phosphorescence enables 10-fold increases in the power obtained from photovoltaic cells, without the need for solar tracking.
Design of efficient molecular organic light-emitting diodes by a high-throughput virtual screening and experimental approach.
TLDR
An integrated organic functional material design process that incorporates theoretical insight, quantum chemistry, cheminformatics, machine learning, industrial expertise, organic synthesis, molecular characterization, device fabrication and optoelectronic testing is reported.
Nuclear methods and the nuclear equation of state
The Brueckner-Bethe-Goldstone expansion, R. Sartor variational methods, S. Fantoni the Dirac-Brueckner approach, R. Brockmann correlations in the nucleon propagation, W. Dickoff Dirac-Brueckner
Integration of Photosynthetic Protein Molecular Complexes in Solid-State Electronic Devices
Plants and photosynthetic bacteria contain protein−molecular complexes that harvest photons with nearly optimum quantum yield and an expected power conversion efficiency exceeding 20%. In this work,
High-efficiency fluorescent organic light-emitting devices using a phosphorescent sensitizer
TLDR
This work uses the mechanism for energetic coupling between phosphorescent and fluorescent molecular species is a long-range, non-radiative energy transfer: the internal efficiency of fluorescence can be as high as 100%.
External Quantum Efficiency Above 100% in a Singlet-Exciton-Fission–Based Organic Photovoltaic Cell
Splitting Singlets Solar cell efficiency is limited because light at wavelengths shorter than the cell's absorption threshold does not channel any of its excess energy into the generated electricity.
EXCITONIC SINGLET-TRIPLET RATIO IN A SEMICONDUCTING ORGANIC THIN FILM
A technique is presented to determine the spin statistics of excitons formed by electrical injection in a semiconducting organic thin film. With the aid of selective addition of luminescent dyes, we
