      abstract     = {The emission spectra of single and polyterbium centers have
                      been measured at the excitation of CaSO4:Tb3+ phosphors with
                      different charge compensators (Na+, calcium vacancies, etc.)
                      by 3.8–35 eV photons or 5 and 300 keV electrons at 6–300
                      K. The possible mechanisms providing quantum yield above
                      unity for green (5D4 → 7FJ) and blue emission (5D3 →
                      7FJ) of Tb3+ at the direct intracenter excitation,
                      excitation of oxyanions or creation of hot (nonrelaxed)
                      electrons and holes have been discussed. On the basis of
                      thermally stimulated luminescence at 6–600 K, the
                      peculiarities of the hopping diffusion of relaxed electrons
                      and holes and their tentative low-temperature self-trapping
                      have been considered.},
