TL;DR: In this paper, high-density silicon nanoparticles were produced in SiNx thin films by chemical vapor deposition on cold substrates and strong room-temperature photoluminescence was observed in the whole visible light range.

TL;DR: In this paper, the authors show that a target with subwavelength nanolayered front can reduce the reflection and increase the absorption of the energy of an intense short laser pulse.

TL;DR: Wei et al. as discussed by the authors investigated the laser interaction with a nanobrush target plasma at the SILEX-I laser facility and showed that a layered surface structure can increase the efficiency of laser energy absorption, and the resulting fast electrons are tightly collimated and guided by the plasma layers to a cross section of about the laser spot size.

TL;DR: In this paper, the authors investigated the energy absorption by the nanolayer in both too-low and too-high laser intensities, and the dependence of the conversion efficiency and hot-electron number on the duration of the (short) laser pulse and the length of the nan-layer length is discussed.

TL;DR: The experimental evidence on one order of magnitude enhancement of intense laser-accelerated proton beam stopping in dense ionized matter is reported, in comparison with the current-widely used models describing individual ion stopping in matter.
