英文摘要The recent discovery of room temperature superconductivity (283 K) in carbonaceous sulfur hydride (C-S-H) has attracted much interest in ternary hydrogen rich materials. In this report, ternary hydride P-S-H was synthesized through a photothermal-chemical reaction from elemental sulfur (S), phosphorus (P) and molecular hydrogen (H-2) at high pressures and room temperature. Raman spectroscopy under pressure shows that H2S and PH3 compounds are synthesized after laser heating at 0.9 GPa, and a ternary van der Waals compound P-S-H is synthesized with further compression to 4.6 GPa. The P-S-H compound is probably a mixed alloy of PH3 and (H2S)(2)H-2 with a guest-host structure similar to the C-S-H system. The ternary hydride can persist up to 35.6 GPa at least and shows two phase transitions at approximately 23.6 GPa and 32.8 GPa, respectively.
