“…Thus, such system has been widely investigated and silicate phosphors with various colors have been well recorded in documents. [11][12][13][14][15][16][17] We also reported some LLPs in the silicate system, where Li 2 SrSiO 4 and Li 2 Ca 0.6 Sr 0.4 SiO 4 were suggested as excellent hosts for LLPs. 18,19 It is also recommended that the phosphorescence of Ce 3+ in most of the hosts is caused by the 5d-2 F 5/2 and 5d-2 F 7/2 energy-level transitions.…”

A blue emitting phosphor Li 2 Sr 0.9 Mg 0.1 SiO 4 :Ce 3+ , with long persistence, was synthesized via a hightemperature solid phase method. According to the X-ray diffraction analysis result, the introduction of Mg 2+ and Ce 3+ ions has no influence on the structure of the host material. Typical 5d-2 F 5/2 and 5d-2 F 7/2 transitions of Ce 3+ ions were detected by PL spectra, which corresponded to the CIE chromaticity coordinates of x ¼ 0.1584, y ¼ 0.0338. An optimal doping concentration of Ce 3+ was determined as of 0.4 at%. Furthermore, the Li 2 Sr 0.9 Mg 0.1 SiO 4 :Ce 3+ phosphor showed a typical triple-exponential afterglow behavior when the UV source was switched off. The highest lifetime of the electrons within the material reached a value of 73.9 s. Thermal stimulated luminescence study indicated that the afterglow of Li 2 Sr 0.9 Mg 0.1 SiO 4 :Ce 3+ was due to the recombination of the electrons with holes released from the traps generated by the doping of Ce 3+ ions in the Li 2 Sr 0.9 Mg 0.1 SiO 4 host. The afterglow mechanism of Li 2 Sr 0.9 Mg 0.1 SiO 4 :Ce 3+ is illustrated and discussed in detail on the basis of the experimental results. Fig. 6 Schematic graph of phosphorescence mechanism.

“…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.…”
