TL;DR: In this paper, the authors demonstrate that electrochemically etched, hydrogen capped SinHx clusters with n larger than 20 are obtained within a family of discrete sizes, which are 1.0 (Si29), 1.67 (Si123), 2.15, 2.9, and 3.7 nm in diameter.

TL;DR: In this article, the authors dispersed electrochemical etched silicon into a colloid of ultrasmall ultrabright Si nanoparticles, and showed that the particles were passivated with hydrogen.

TL;DR: In this article, a colloid of ultrabright blue luminescent nanoparticles (1 nm in diameter) was reconstituted into films or microcrystallites, and the results were discussed in terms of population inversion, produced by quantum tunneling or/and thermal activation, and stimulated emission in the quantum confinement-engineered Si-Si phase found only on ultrasmall Si nanoparticles.

TL;DR: In this paper, a colloid of ultrasmall blue luminescent nanoparticles, observable with the naked eye, in room light was detected using two-photon near-infrared femtosecond excitation at 780 nm.

TL;DR: In this paper, trilathin films of highly monodispersed luminescent Si nanoparticles are directly integrated on polycrystalline Si solar cells, and the authors monitor the open-circuit voltage and short circuit current.
