Co-doping effect of Ce ions on Eu ion-doped Sr2SnO4 in terms of emission color tunability and intensity modulation

Structural, microstructure, dielectric relaxation, and AC conduction studies of perovskite SrSnO3 and Ruddlesden–Popper oxide Sr2SnO4

“…14 Recently, Sr 2 SnO 4 has been reported to be optically inert and can serve as a host material, whereby the incorporation of rare earth ion activators (Ce 4+ , La 3+ , Eu 3+ , Nd 3+ , and Sm 3+ ) has enabled its phosphor application in display devices, visible light-emitting diodes, and in in vivo and in vitro imaging in biomedical applications. 13,15–18 Modification at both lattice sites Sr and Sn of Sr 2 SnO 4 by rare earth ions has been explored for green emission phosphors (Sr 2 SnO 4 :Eu 3+ ), mixed ionic and electronic conductors (Sr 2 SnO 4 :La 3+ ), ferromagnetism (Sr 2 SnO 4 :Nd 3+ ), thermally stable capacitors (Sr 2 SnO 4 :Ba 2+ ), and electronic device applications. 19–22…”

Role of charge-compensation process on the structural, microstructure and electrical properties of pure and Nb-doped Sr2SnO4

“…The pristine phase of Sr 2 SnO 4 has been well explored as a host material for phosphor application, and with the substitution of rare earth ions, their phosphor application has been modified for different optical imaging and display device applications [24][25][26][27]. Depending on the desired properties, the semiconductor material Sr 2 SnO 4 has been tuned for its electrical, optical, and electronic properties, making this a potential application in electrical, electronic, and optoelectronic devices [11,13,14,28,29].…”

“…The emission intensity of Eu 3+ was drastically enhanced by the substation of Ce 3+ due to energy transfer from Ce 3+ to Eu 3+ . The charge transfer processes were well established for the tuning of colours emitted by phosphor from blue to orange [27].…”
