TL;DR: In this article, an intramolecular charge transfer (CT) was used to inhibit the fluorescence and laser emission in the derivatives with an amino terminal group in the side chain, and a high lasing efficiency in the green-blue zone of the spectrum was obtained with a N 2 pulsed laser.

TL;DR: The notion and usefulness of the effective dielectric constant in silicon nanocrystallites are analyzed using a self-consistent linear screening calculation of hydrogenic impurities and the consequences of charging effects on carrier injection are discussed and shown to be important.

TL;DR: Theoretical and experimental results provided evidence for fast Auger recombination in silicon nanocrystallites as mentioned in this paper, which gave nonradiative lifetimes in the 1 ns range.

TL;DR: In this paper, two important observations for porous silicon, the saturation and the voltage selective quenching of photoluminescence, are presented and discussed in two phenomenological models: the saturation of the absorption and an Auger effect.

TL;DR: In this article, the effect of dangling bonds at the surface and denor (or acceptor) impurities on the radiative lifetime of silicon crystallites is discussed, with particular emphasis on porous silicon.
