On the role of traps in the BaMgAl10O17:Eu2+ fluorescence mechanisms

Characteristics of photoluminescence, thermoluminescence and thermal degradation in Eu-doped BaMgAl10O17 and SrMgAl10O17

“…Bizarri and Moine [8] reported that the electron trap in BAM:Eu have a positive influence on its luminescence efficiency. This indicated that the electron trap in BAM:Eu is the path way for energy transfer from host to Eu ions.…”

One-dimensional hollow SrS nanostructure with red long-lasting phosphorescence

“…5(b), respectively. These sub-peaks are corresponded to the well-known electronic transitions between the splitted 4f 6 5d configuration and the ground state of 4f 7 of Eu 2+ ions [18]. Fig.…”

Crystal structure, thermally stability and photoluminescence properties of novel Sr10(PO4)6O:Eu2+ phosphors

“…4. It is found that the PLE spectrum is composed of strong broad absorption bands from 220 to 425 nm in UV and n-UV range attributed to 4f 7 ( 8 S 7/2 )-4f 6 5d transitions of the doped Eu 2 þ ions [18]. Upon the excitation at 346 nm, the phosphor presents a broad blue emission band peaked at 439 nm extending from 400 to 550 nm, which is attributed to the 4f 6 5d-4f 7 transition of Eu 2 þ .…”
