“…We would also like to note that, to the best of our knowledge, there are no reports devoted to the PL analysis of undoped crystalline zinc phosphate. In fact, this material has been mostly used as a host for rare earth or transition metal ions incorporation for luminescence applications, as in the case of the Dy 3+ sensitized β-Zn3(PO4)2:Mn red long persistent phosphor [77] or the zinc phosphate glasses doped with Sm 3+ and Eu 3+ for lighting applications [78].…”

“…Long persistent luminescence (LPL) is a particular optical phenomenon whereby a material remains luminescence for an appreciable time after the high energy excitation removed [1][2][3][4][5][6]. The first record of an LPL material, which was found in nature, was during the Song Dynasty of China (11 th century A.D.) [7].…”

A novel red emitting long persistent luminescent phosphor Ca 2 Ga 2 GeO 7 :Pr 3+ (2217) was developed by solid state method at 1300 °C in air. The refined crystal structure of Ca 2 Ga 2 GeO 7 host was solved. The intense red long persistent luminescence originates from the f-f transitions of Pr 3+ centers at highly disordered Ca 2+ sites in CaO 8 polyhedrons. It can be properly recorded for 1.5 h by the definition of 0.32 mcd/m 2 and is actually visible for more than 5 h by dark-adapted vision in darkness. At least one type of intrinsic lattice defects of the Ca 2 Ga 2 GeO 7 host as proper shallow traps exists in Ca 2 Ga 2 GeO 7 :Pr 3+ material and the depth of the traps is calculated to be 0.59 eV, which is very suitable for long persistent luminescence. It reveals that the Pr 3+ dopants not only act as emitters but also increase the density of these significant intrinsic traps, resulting in the efficient persistent luminescence of Pr 3+. The

Numerous challenges persist in the field of long persistent luminescence (LPL) materials, including the unclear mechanism of persistent luminescence, low efficiency of sunlight excitation, and limited availability of commercial materials. To address these issues, a LPL material, SrAl2Si2O8:x% Eu2+,y% Dy3+, is synthesized for excitation by UV lamps or sunlight. Dy3+ doping remarkably extends the afterglow duration from 2 to 7 h under UV lamp excitation, exhibiting a remarkable enhancement of 350%. Notably, SrAl2Si2O8:4.0% Eu2+, 3.0% Dy3+ shows 2 h afterglow duration when exposed to sunlight, surpassing other LPL materials and expanding potential applications. XPS and XANES measurements confirm Eu2+ as the luminescent and persistent luminescent centers, while Dy3+ increases trap diversity. Through meticulous analysis of the EPR and XPS data, it is elucidated that the material encompasses two distinct types of traps, namely oxygen vacancies and may be traps. This provides a basis for subsequent trap analysis in LPL materials. Microstructural analysis examined ion coordination environment changes due to Eu2+ and Dy3+ doping. The mechanical luminescent properties are characterized, and a plausible afterglow mechanism is proposed based on the experimental results, offering insights for further research into LPL materials.
