Dye capped semiconductor nanoclusters. role of back electron transfer in the photosensitization of sno2 nanocrystallites with cresyl violet aggregates
TL;DR: In this article, the back electron transfer between the photoinjected electron and the oxidized sensitizer plays an important role in controlling the efficiency of net electron transfer, and it is shown that most of the transfer is multiexponential and most is completed within a few hundred nanoseconds.

An experimental study of the primary parameters that determine the temporal compression of CW Nd:YAG laser pulses
TL;DR: In this paper, an experimental study of temporally compressed CW Nd:YAG laser pulses using an optical fibre and diffraction grating pair technique has been carried out, where the relevant experimental parameters have been varied so that a better insight into the physical processes could be gained and to enable some comparisons to be made with theory.
