Energy transfer mechanism from Gd³⁺ to Sm³⁺ in K₃Gd(PO₄)₂:Sm³⁺ phosphor

Synthesis, crystal structure and luminescence properties of a new samarium borate phosphate, CsNa2Sm2(BO3)(PO4)2

“…4 G 9/2 and 6 H 5/2 ! 4 I 13/2 intra-configurational 4f!4f transitions, respectively, of Sm 3+ ions (Gupta et al, 2015;Zhao et al, 2020a). Among these, the 6 H 5/2 !…”

Luminescence of Agrellite Specimen from the Kipawa River Locality

“…After using laser induction [4], time-resolved measurements of the Gd 3+ fluorescence for zircon, anhydrite, and hardystonite have been prepared. The energy transfer among Gd 3+ and many RE 3+ have been analyzed [10][11][12][13][14][15][16][17][18][19][20][21][22][23][24][25][26][27]. For the studied agrellite sample, the energy transfer from Gd 3+ to RE 3+ could be excluded.…”

A bidentate-anionic-group strategy for enhancing electron–phonon coupling and vibronic fluorescence in rare-earth crystals

“…K 3 Gd(PO 4 ) 2 crystallizes in the monoclinic P 2 /m space group. 38,39 Every Gd 3+ ion coordinates with seven adjacent O atoms from one bidentate-PO 4 and five monodentate-PO 4 tetrahedra to constitute a [GdO 7 ] 11À polyhedron, and the Gd-O bond lengths range from 2.287 to 2.516 Å (Fig. 6(a)).…”
