Well-tuned white-light-emitting behaviours in multicenter-Ln polyoxometalate derivatives: A photoluminescence property and energy transfer pathway study

Recent advances in lanthanide-based POMs for photoluminescent applications

“…Note that the triple-Ln III ion, due to the optimal doping ratio obtained in Dy 0.8 Er 0.2 -POM , showed the best photostability. Moreover, the triple-Ln III ion-doped POM derivatives, [Eu x Tb y Tm 1− x − y (C 7 H 5 O 2 )(H 2 O) 2 (PW 11 O 39 )] 5− , 76 representing a relatively high energy transfer efficiency between Eu III and Tb III ions.…”

“…68 The multicenter-Ln co-doped [Eu x Tb y Tm 1− x − y (C 7 H 5 O 2 )(H 2 O) 2 (PW 11 O 39 )] 5− have been synthesized to study the white-light-emitting behavior with the molar ratio of Eu III /Tb III /Tm III = 0.06 : 0.10 : 0.84. 76…”

Application of Polyoxometalate-based composites for sensor systems: A review

“…POMs, on the other hand, have been discovered to play a key part in the extraordinary development of PCMs having greater efficiency and stability. PCMs are also being used to create neoteric smart structures for applications such as optics [10,11,14], pharmaceuticals [15][16][17], energy-related applications [18][19][20], sensors [21][22][23], and green catalysis [24][25][26] (Fig. 1).…”

Roles of Organic Fragments in Redirecting Crystal/Molecular Structures of Inorganic–Organic Hybrids Based on Lacunary Keggin-Type Polyoxometalates

“…Bulky ligands containing carboxylate groups may rarely show the bridging effect [ 134 , 135 ]. It was observed that pyridine-4-carboxylic acid can only substitute the water molecules that were coordinated to the bridging lanthanide cation in the structure of [REK(H 2 O) 12 ][RE(H 2 O) 6 ] 2 [(H 2 O) 4 RE(BW 11 O 39 H)] 2 ∙20H 2 O due to the to the steric encumbrance [ 136 ].…”
