Abstract

The energy migration in the frozen polymer Poly(G) doped with Tb 3+ ions-energy traps is studied at 77 K. It is shown that the decay of the Tb 3+ luminescence is in good agreement with the theory of migration in low-dimensional systems. The approximation gives the upper limit of the jump rate to be 1.2 × 10 5 s −1. The influence of the energy disordering upon the excitation migration along the polymer chain is discussed.
