Synthesis and luminescence properties of Eu2+-doped Li2SrSiO4

Photoluminescence and afterglow behavior of Tb 3+ activated Li 2 SrSiO 4 phosphor

“…Thus it has been widely investigated [10][11][12][13][14][15][16]. Tb 3+ has been widely used as green-emitting activator for luminescent materials due to the transition from 5 D 4 to 7 F j energy-levels [17].However the long lasting phosphorescence of rare-earth ions doped Alkaline-earth lithium silicates has not been reported yet.…”

Luminescence behavior of Li2Sr1‐3x/2EuxSiO4 red phosphors for LED applications

“…Rare earth doped silicate Li 2 MSiO 4 (M = Ca, Sr and Ba) phosphors have been developed as a promising phosphor for white LED applications (10)(11)(12)(13)(14)(15)(16)(17)(18)(19)(20)(21)(22)(23)(24)(25)(26)(27). In particular, Li 2 SrSiO 4 is considered an ideal host owing to its relative lower synthesis temperature, and higher thermal and chemical stability (14)(15)(16)(17)(18)(19)(20)(21)(22)(23)(24)(25)(26)(27). To date, most studies have focused on the luminescent properties of Eu 2+ and/or Ce 3+ ions in the Li 2 SrSiO 4 host (14)(15)(16)(17)(18)(19)(20)(21)(22).…”

For example, the promising Li 2 SrSiO 4 :Eu 2+ phosphor showed a broad band emission with a maximum at about 570 nm (excited at 380-460 nm); thus quite efficient white LEDs can be fabricated using a combination of (In,Ga)N chips and Li 2 SrSiO 4 :Eu 2+ as a yellow-orange phosphor (14)(15)(16).…”

A Nanostructure Phosphor: Effect of Process Parameters on the Photoluminescence Properties for Near-UV WLED Applications

“…In past several decades, researches have focused on the rare-earth (Re) ion-doped silicate-based phosphors [10][11][12][13][14] as inorganic functional materials. Among them, the Eu iondoped strontium silicate phosphors seem to have considerable potential for application in various optical devices [15][16][17][18][19] . The Eu 3?…”
