Photoactivated Fluorescence from Individual Silver Nanoclusters.
TL;DR: Fluorescence microscopy of nanoscale silver oxide (Ag2O) reveals strong photoactivated emission for excitation wavelengths shorter than 520 nanometers as discussed by the authors, and the individual luminescent species are thought to be silver nanoclusters that are photochemically generated from the oxide.

The effect of Auger heating on intraband carrier relaxation in semiconductor quantum rods
TL;DR: In this article, the authors report the first experimental observation of efficient Auger heating in CdSe quantum rods at high pump intensities, leading to a strong reduction of carrier cooling rates.
Narrow-bandwidth spontaneous luminescence from oriented semiconducting polymer nanostructures

Photophysics and intramolecular excimer formation in a constrained anthracenyl diadduct
TL;DR: The photophysical properties of N, N '-di(9-anthracylmethyl)hexahydropyrimidine 1 and its analogues are reported in this paper, where electronic spectra and kinetics of these compounds are studied over a range of solvent and temperature conditions.
