Energy transfer from Tb3+ to Eu3+ ions sorbed on SrTiO3 surface

White emitting phosphors based on glasses of the type 10AlF3–10TiO2–39PbO–30H3BO3–10SiO2–xEu2O3–(1−x)Tb2O3: An energy transfer study

“…Since both the bands have near the same half-width equal to 600 cm À 1 , the resonance could be very effective. This observation was confirmed by Garcia-Rosales et al [20] and Kukliński et al [19].…”

Crystal growth and photoluminescence of europium-doped strontium titanate prepared by a microwave hydrothermal method

“…This broad band luminescence is usually observed in perovskite crystals, associated with the presence of imperfections or defects, and is typical of a multiphonon and multilevel process. In particular, SrTiO 3 can accommodate rare-earth ions in the structure; hence, this doping is not only used as a probe to investigate local centers and energy, but also to cause changes in the optical behavior of these materials [24].…”

Structure, morphology and photoluminescence emissions of ZnMoO4: RE 3+=Tb3+ - Tm3+ - X Eu3+ (x = 1, 1.5, 2, 2.5 and 3 mol%) particles obtained by the sonochemical method

“…The specific conditions must be fulfilled for this mechanism to take place. Note the following points: (I) the emission range of D is partially superimposed on the absorption range of A, and (II) the distance (Rc) between D and A must be sufficiently short, since the energy transfer efficiency is proportional to 1 Rc 6 , to allow the interaction of the multipole-multipole emission bands of material [75,76]. The Forster resonance energy transfer can usually happen at distances of up to 100 Å. Dexter (also known as exchange or coalitional energy transfer) is another dynamic quenching mechanism.…”
