Abstract
The preparation of new types of nanosystems based on metallic yttrium nanoparticles, which are difficult to produce by traditional methods due to the high melting temperature and the extremely high oxidizability of this metal, has been studied. The materials were prepared with an original high vacuum set-up (LUCAS) intended for the formation of metal nanoparticle beams by laser ablation. Yttrium nanoparticles were synthesized, and their chemical reactions with hydrogen were studied at room temperature. It was found that the reaction at low hydrogen pressures (~10−3 Pa) leads to the formation of YH2 dihydride particles with metallic properties and optical plasmon absorption. An increase in the hydrogen pressure to ~100 Pa results in the transformation of metallic-like YH2 nanoparticles to dielectric YH3−x (x < 1) nanoparticles. It is shown that the last reaction corresponding to the metal–dielectric phase transition is reversible with respect to the hydrogen pressure. These experimental data demonstrate that yttrium nanoparticle materials can be effectively used as optical hydrogen gas sensors.
