The optical absorption spectrum of b-Ga 2 Se 3 has been measured at pressures up to 7 GPa using a diamond anvil cell. The exciton absorption is observed in the optical absorption spectrum at ambient pressure. With increasing pressure, the exciton line shifts to the higher energy region. From the shi
