The phosphorescence from benzophenone crystals has been studied as a function of pressure at 77°K. Squeezing the crystal irreversibly replaces exciton phosphorescence by defect phosphorescence, characterized by a ∼ 1000-cm−1 trap depth and a lifetime of 3.7 msec. The pressure effect on the defect phosphorescence is Δν = − 490 cm−1 and Δτ = − 0.5 msec for ΔP = 30 kbar.
