Quenching ofTb3+Luminescence by Direct Transfer and Migration in Aluminum Garnets

Excited states and energy transfer from donor cations to rare earths in the condensed phase

“…Migration effects of energy were found by Van der Ziel et al (45) in terbium-doped aluminium garnets. The migration of energy is temperature sensitive and becomes dominant at 297 K.…”

Controllable synthesis and luminescent properties of three-dimensional nanostructured CaWO4:Tb3+ microspheres

“…7 F 6 + 5 D 4 (ET-III) as shown in Fig. 8 where the energy levels and the energy transfer channels are clearly illustrated, are usually existent and have been widely studied [34][35][36][37]. It is known that the energy transfers involving 5 D 3 level (ET-I and ET-II) are electric dipole-dipole interaction processes, the ET-III is energy migration process based on the exchange interaction [38][39][40][41][42].…”

Crystal, electronic structures, optical and magnetic properties of Tb4Al2O9

“…Tb 3 Al 5 O 12 itself shows typical green line emission mainly originating from the 5 D 4 → 7 F J transition of Tb 3+ [5]. In addition, Tb 3 Al 5 O 12 was found to be a good host for the Ce 3+ activator (TAG:Ce 3+ ).…”
