Effect of RE3+ as a co-dopant in long-lasting phosphorescence CdSiO3:Mn2+ (RE=Y, La, Gd, Lu)

Sol–gel synthesis and luminescence properties of CdSiO3: Mn2+, Eu3+ phosphor

“…Up to now, most CdSiO 3 phosphors have been prepared by conventional solid-state synthesis route [14][15][16][17]. However, it should be noted that there are certain unavoidable issues with the solid-state synthesis method, such as energy-consuming, inhomogeneous mixing and product with irregularly shaped and aggregated particles [18,19].…”

Preparation and properties of CdSiO3:Mn2+, Dy3+ phosphor

“…Due to the nonequivalent substitution, long-lasting phosphorescence or photoluminescence performance can be improved greatly [11]. The crystal structure of CdSiO 3 is expected to be onedimensional chain of edge-sharing SiO 4 tetrahedron.…”

“…Some rare-earth ions can be worked as suitable trap levels to prolong the decay time of the phosphors, the relative work are being processed, such as CdSiO 3 :Sm 3+ [13], CdSiO 3 :Pr 3+ [14], and CdSiO 3 :Mn 2+ , RE 3+ (RE = Y, La, Gd, Lu) [11]. Beside the rare-earth ions-doped phosphors, the manganese ions-doped materials are good candidates for photonic sources.…”

Luminescence properties of CdSiO3: Mn2+, RE3+ (RE=Sm, Dy, Eu) phosphors

“…Due to the nonequivalent substitution, long-lasting phosphorescence or photoluminescence performance can be improved greatly [9]. The crystal structure of CdSiO 3 is expected to be onedimensional chain of edge-sharing SiO 4 tetrahedron.…”

“…[10]. Recently, much attention has been paid to manganese ionsdoped and rare-earth-ion-doped CdSiO 3 as efficient luminescent materials, e.g., CdSiO 3 : Sm 3+ [11], CdSiO 3 : Mn 2+ [12], CdSiO 3 : Pr 3+ [13], CdSiO 3 : Mn 2+ , RE 3+ (RE = Y, La, Gd, Lu) [9].…”
