Intermolecular energy transfer and photostability of luminescence-tuneable multicolour PMMA films doped with lanthanide–β-diketonate complexes
TL;DR: In this paper, the preparation, characterisation and photoluminescence study of poly(methylmethacrylate) (PMMA) thin films co-doped with [Eu(tta)3(H2O)2] and [Tb(acac) 3(H 2O)3] complexes was reported.

TL;DR: In this paper, high-luminescent rare earth (R3+) doped alkaline-earth tungstates MWO4:R3+ (M2+: Ca, Sr and Ba, R3+: Eu, Tb, Gd) were prepared with a room temperature coprecipitation method and the phosphors were characterized by X-ray powder diffraction (XPD), thermal analysis (TG), infrared absorption spectroscopy (FTIR), and UV excited photoluminescence.

White emission phosphors based on Dy3+-doped into anhydrous rare-earth benzenetricarboxylate complexes
TL;DR: In this article, trimesic acid ligands (TMA) were used as luminescent sensitizer in the intramolecular energy transfer of rare earth anhydrous complexes RE(TMA):Dy3+ (RE3+ = Y3+ and Lu3+) containing the TMA.
