“…Average size of the particle found to be 65nm which is calculated from Debye -Schrieffer formula D= β Cosθ / 4Sinθ. Where β is the full width at half maximum.The impurity peaks at 25 might be due to Sr 3 Al 2 O 6 [17]. This is due to evolution of heat during combustion reaction.…”

“…It was reported that the emission spectra of the phosphors alkaline earth aluminate doped Eu 2+ ion had a broad band that characterized the transition of electronic configuration from 4f 6 5d 1 to 4f 7 of Eu 2+ ion [2][3][4][5]. The photoluminescence of materials have a strong dependence on crystal field [3][4][5].…”

“…The long-lasting afterglow of these materials have been studied by co-doped the rare earth ions [2][3][4][5]. The long persistent phosphors have more important applications with their long afterglow.…”

“…Farhikhteh et al 8 , and Thanguruju et al 32 reported that the pH of the precursor solution can strongly effect the morphology and surface area of particles. Chen et al 33 found the shape of porous particles can be controlled by adjusting the ratio of solvents in the precursor solution. The sol-gel method provides extensive control over the stoichiometry and structure due to the even dispersion of precursor metals.…”
