An efficient yellow-emitting vanadate Cs 5 V 3 O 10 under UV light and X-ray excitation

Rare-earth free self-luminescent Ca2KZn2(VO4)3 phosphors for intense white light-emitting diodes

“…In the vanadate cluster, the central metal ion is surrounded by four oxygen ions in tetrahedral symmetry ( T d ). In some of the vanadate compounds, an unusual luminescent property was observed, i.e., a broad and intense charge transfer (CT) band due to the charge transfer from O 2− ligand anion to V 5+ in the NUV range, thereby yielding a broad emission band over the entire visible range (400–700 nm)3637. Furthermore, these materials have considerable advantages over conventional phosphor materials, including low cost and energy efficiency (due to low calcination temperature) as well as broadband emission to obtain high CRI3839.…”

A vanadate-based white light emitting luminescent material for temperature sensing

“…5(b). The excitation peak of [VO 4 ] 3À is asymmetric and can be decomposed into two Gaussian components Ex 1 ( 1 A 1 / 1 T 1 , 276 nm) and Ex 2 ( 1 A 1 / 1 T 2 , 314 nm) corresponding to the intrinsic transitions in VO 4 tetrahedron 43,44 as shown in the diagram of Fig. 6.…”

New lanthanide‐free self‐activated full‐color emission phosphor in Y3+ doped Sr3Bi(VO4)3 system for white light emitting diode applications

“…[ 10,11 ] Recently many vanadates have been reported as self‐activated phosphors without any lanthanide dopant. [ 12–18 ] They exhibit broad emission bands in the visible region from blue to red which makes them suitable as full‐color emission phosphors for WLEDs. Ronda and Blasse studied many vanadate‐based phosphors and assigned the electronic transition in a [VO 4 ] 3− tetrahedron as 1 A 1 → 1 T 2 and 1 A 1 → 1 T 1 for the excitation process and 3 T 2 → 1 A 1 and 3 T 1 → 1 A 1 for the emission.…”
