在室温和近型压力下的超导性是物理和材料科学中极为受欢迎的现象。A recent study reported the presence of this phenomenon in N-doped lutetium hydride [ Nature 615, 244 (2023)], however, subsequent experimental and theoretical investigations have yielded inconsistent results.This study undertakes a systematic examination of synthesis methods involving high temperatures and pressures, leading to insights into the impact of the reaction path on the products and the construction of a phase diagram for lutetium hydrides.Notably, the high-pressure phase of face-centered cubic LuH 3 (fcc-LuH 3 ) is maintained to ambient conditions through a high-temperature and high-pressure method.Based on temperature and anharmonic effects corrections, the lattice dynamic calculations demonstrate the stability of fcc-LuH 3 at ambient conditions.然而，在环境压力下，在FCC-LUH 3中，在2 K和磁化测量中未观察到超导性。This work establishes a comprehensive synthesis approach for lutetium hydrides, thereby enhancing the understanding of the high-temperature and high-pressure method employed in hydrides with superconductivity deeply.
