a Convex hull diagrams as a function of pressure for compositions in the range LuH0 to LuH3. Dark blue circles indicate thermodynamically stable structures and red circles indicate metastable structures. The dashed vertical lines for selected stoichiometries are shown for guidance only. b Colour of LuHn compounds as a function of pressure. c Reflectivity of LuHn compounds as a function of pressure.
