Picosecond Time-Resolved Photoluminescence of Zinc Oxide Single Crystals, Films and Nanoparticles

, 2003
Zinc oxide (ZnO) is a refractory semiconductor material whose band gap is both wide (3.39 eV) and direct. It is under consideration as a promising material for blue/uv semiconducting light emitting diodes (LEDs) and lasers.

When Poor Exciton Dissociation Limits Photocurrents in Organic Solar Cells: Why Low Offset Non‐Fullerene Acceptor Blends Can't Be Efficient

Advanced Materials, EarlyView.
The energetic offset between the donor and the acceptor components in organic photoactive layers is central to the tradeoff between photovoltage and photocurrent losses. This Perspective covers the most important issues surrounding this topic in non‐fullerene acceptor blends, from the difficulty of accurately determining state energies and driving ...

Photoluminescence and photostimulated luminescence of BaFBr:Eu2+,Eu3+

, 1997
In the photoluminescence (PL) of BaFBr:Eu2+,Eu3+, the emissions of Ea(2+), carrier electron-hole (e-h) recombination, and Eu3+ are observed, while in the photostimulated luminescence (PSL) only the emission of Eu2+ is exhibited. This disappearance of e-h
