TL;DR: Using rare earth coordination polymers with salicylic acid as precursors for the luminescent species Gd2SiO5:Tb3+, composing with the polyacrylamide as dispersing media, nanophosphor of Gd 2 SiO5 doped with Tb3+ was synthesized by the sol-gel technique as discussed by the authors.

TL;DR: Five novel lanthanide complexes with 2, 2′-bipyridine-N, N′-dioxide (bipyO2) were synthesized and characterized by elemental analysis, IR spectrum, and photophysical properties indicated that the triplet state energy of the ligand is suitable for the sensitization of the luminescence of Eu3+, Tb3+, Sm3+ and Dy3+.
Abstract: Five novel lanthanide (Eu3+, Tb3+, Gd3+, Sm3+ and Dy3+) complexes with 2, 2′-bipyridine-N, N′-dioxide (bipyO2) were synthesized and characterized by elemental analysis, IR spectrum. The triplet state energy of bipy O2 was determined to be 22275 cm−1 with the phosphorescence spectrum of bipy O2 and its gadolinium complex. The photophysical properties of these complexes indicated that the triplet state energy of the ligand is suitable for the sensitization of the luminescence of Eu3+, Tb3+, Sm3+ and Dy3+, especially of Tb3+.

TL;DR: Using rare earth coordination polymers with salicylic acid and rare earth nitrates as precursors for the luminescent species Y x Gd 2− x O 3 :Eu 3+, composed with the polyvinyl alcohol (PVA) as dispersing media, nanophosphors of Y 2 O 3, with different ratio of Y and Gd were synthesized as discussed by the authors.
