A bacterial cellulose-based LiSrVO4:Eu3+ nanosensor platform for smartphone sensing of levodopa and dopamine: point-of-care diagnosis of Parkinson's disease

“…44 The peak centered at 812 cm −1 corresponds to the absorption band of the (VO 4 ) 3− group, which arises from the V–O stretching vibrational absorption band. 45 Moreover, the two peaks at 1019 cm −1 and 1140 cm −1 correlate to the VO bond's stretching vibration. 46,47 The broad band corresponds to the bending vibrations of H–O–H in the range of 1300–1700 cm −1 , whereas the broad peak centered about 3430 cm −1 belongs to the stretching vibrations of OH, which can be caused by the physical absorption of moisture.…”

Structural, photoluminescence, and photocatalytic performances of Ce3+‐activated orthovanadate oxides M3(VO4)2 (M: Mg or Zn) synthesized by solution combustion route

“…Furthermore, the absorption bands observed in the range of 900–500 cm −1 were associated with the tetrahedral VO 4 vibration modes in the network [20]. Specifically, the bands at ~865, 863, and 855 cm −1 were attributed to the V–O stretching vibrations in the VO 4 group [21, 22], while the bands at ~780, 689, 685, and 529 cm −1 were linked to the asymmetric vibrations of the VO 4 group [23, 24]. Other distinct bands located at ~1383, 1364, and 1215 cm −1 corresponded to the C–O stretching vibrations, whereas the bands at ~1748, 1647, and 1643 cm −1 were attributed to the C=O stretching bonds [25, 26].…”

“…Furthermore, the absorption bands observed in the range of 900-500 cm À1 were associated with the tetrahedral VO 4 vibration modes in the network [20]. Specifically, the bands at $865, 863, and 855 cm À1 were attributed to the V-O stretching vibrations in the VO 4 group [21,22], while the bands at $780, 689, 685, and 529 cm À1…”

Physicochemical Characterization of the Hybrid Molybdate–Tungstate Materials for Solid-State Lighting

“…Among trivalent rare earth ions, samarium (Sm 3+ ) and europium (Eu 3+ ), thanks to their unique energy-level structures, play important roles in the development of luminescent materials for many different applications . The samarium ions are typically efficient activators that produce excellent orange-red emission. − Their emission spectra show three characteristic peaks described as 4 G 5/2 → 6 H 5/2 , 4 G 5/2 → 6 H 7/2 , and 4 G 5/2 → 6 H 9/2 transitions …”
