Abstract
We have investigated the pressure-volume relationship in YbO to 35 GPa using a diamond anvil cell and the energy dispersive X-ray diffraction technique. The anomalous compressibility exhibited by YbO above 8 GPa strongly suggests a valence change in Yb from divalent towards the trivalent state at higher pressures. The valence change appears to be continuous. The change in color from black to yellow in reflected light supports the valence change. The initial bulk modulus of YbO is B0 = 130 ± 10 GPa.
