We study the temporal behaviour of donors in DET fluorescence embedded in restricted-geometry objects, particulary around the crossover time t(cr) to see the differences between the behaviour of regular restricted-geometry objects and that of actual fractal structures. All the objects show fractional apparent dimensions at around t(cr). The apparent dimensions of the fractal objects in addition have a periodic oscillation the peaks of which exceed the dimensions of the embedding space.
