Synthesis. of luminescent sillicon clusters by spark ablation
نویسندگان
چکیده
The synthesis of luminescent nanometer-scale Si clusters by spark ablation from a crystalline Si substrate is described. The cluster source, described in the text, generates clusters in a flowing Ar stream at atmospheric‘ pressure. Electron microscopy reveals that the clusters have diameters in the 2-4 nm size range. The luminescence spectra of the clusters, similar to that of porous Si, are presented.

Synthesis of spherical luminescent particulate coatings
In this communication, we show the feasibility of the pulsed laser ablation technique to make very thin, uniform luminescent coatings on particulate systems. To deposit continuous particulate coatings, the laser-induced plume from the target comes in contact with an agitated bed of core particles ~size 1 mm!. The pressure and nature of the background gas ~inert or active! controls the cluster s...

In this study, B4C / SiC nanocomposite powder with 1 to 1 molar ratio was synthesized completely in situ, with high purity and at low temperature by mechanical activation volume combustion synthesis method. At first, raw materials consist of B2O3, Mg, C and Si were weighed. The weighed materials were mixed and milled for 9 hours by planetary ball mil and under argon atmosphere. Milled materials...
متن کاملFacile and rapid synthesis of highly luminescent nanoparticles via pulsed laser ablation in liquid.
This paper demonstrates the usefulness of pulsed laser ablation in liquids as a fast screening synthesis method able to prepare even complex compositions at the nanoscale. Nanoparticles of Y2O3:Eu3+, Lu2O2S:Eu3+, Gd2SiO5:Ce3+, Lu3TaO7:Gd3+ and Tb3+ are successfully synthesized by pulsed laser ablation in liquids. The phase and stoichiometries of the original materials are preserved while the si...
متن کاملLuminescent iron clusters in solution.
Metal clusters, composed of a few atoms at the core, exhibit unique properties and have potential applications. Although atomically precise clusters of noble metals have been synthesized, analogous systems of reactive metals, such as iron, have not been realized in solution due to high reactivity. Here we report the synthesis and characterization of novel iron clusters in the hemoglobin matrix ...
