Change in the intensity of the irradiation laser pulse did not influence the non-exponential decay profile of benzophenone phosphorescence in poly(methyl methacrylate) at 20 ' ~. This result is incompatible with the biphotonic triplet-triplet annihilation process, but supports the diffusion-controll
