Preparation, Separation, Characterization and Hydrogenation of Endohedral Metallofullerenes
… of EMFs. A family of novel large cage yttrium-based TNT EMFs Y₃N@C₂ₙ (n=40-44) was prepared, separated, and structurally characterized for the first time. The structure of Y₃N@C₂ₙ (n=40-44) is proposed by the experimental and computational ¹³C NMR studies. The first ⁸⁹Y NMR results for …

Efficient light emission from bismuth-doped rare earths compounds for Si microphotonics
… faced. Bismuth is proposed as an emitter for Si-based transparent materials in place of the most common used REs, as Eu and Tb: this element indeed can improve much more the optical efficiency of the systems thanks to its peculiar electronic configuration and to its high absorption and emission …
