Preparation and luminescence characteristics of Sr3SiO5:Eu2+ phosphor for white LED

The development of silicate matrix phosphors with broad excitation band for phosphor-convered white LED

“…As the concentration of Eu 2+ increases, however, the emission band of Ba 3 SiO 5 :0.15Eu 2+ phosphor is split into two emission bands with a main peak at 504 nm and a less intense band at 568 nm [36] . Sr 3 SiO 5 :Eu 2+ , as a yellow phosphor, can be excited by 450-470 nm blue light [37][38][39] . Furthermore, it presents broader excitation spectrum and higher excitation efficiency than that of Sr 2 SiO 4 :Eu 2+ (Figure 4(e)) [34] .…”

Influence of halide flux on the crystallinity, microstructure and thermoluminescence properties of CdSiO3:Co2+ nanophosphor

“…Hence the design and fabrication of the nanostructured luminescent materials have received great attention. In recent years, silicate-based nanocrystalline phosphors have attracted researcher's interest due to their advantages such as stable crystal structure, high thermal and chemical stability [1][2][3][4][5][6]. In these silicate frameworks, the metal ion and also the dopants acquire different coordination geometries and hence they show excellent luminescence [7].…”

Luminescent properties of sol–gel processed red‐emitting phosphor Ca0.6Sr0.4–1.5x‐0.5yMo0.4 W0.6O4:EuxLiy

“…Cao et al reported that the luminescent intensities of Eu 3+ and other rare earth co‐doped solid solutions of Ca 0.6 Sr 0.4 (WO 4 ) 1‐x (MoO 4 ) x were higher than that of the Eu 3+ doped solid solutions. Because of the charge defects caused by different electrovalence of Eu 3+ and Ca 2+ /Sr 2+ , the phosphors without charge compensation showed a relatively poor luminescent intensity . To date there are few reports on the solid solution Ca 0.6 Sr 0.4 (WO 4 ) 1‐x (MoO 4 ) x :Eu 3+ using Li + ion as charge compensator.…”
