Synthesis and Sm2+/Sm3+ doping effects on photoluminescence properties of Sr4Al14O25

Template-free hydrothermal synthesis of SrSO4:Sm3+ microrods and its electron trapping luminescence properties

“…According to Figs. 7 and 8, all the peaks in the PSL and PL spectra of SrSO 4 :Sm 3+ can be assigned to the transitions of Sm 3+ ions, while no peak is assigned to the transition of Sm 2+ ions [28][29][30][31][32]. It can be observed that the peak intensity of samples decreases with increasing the size, which is similar to the results by Samaele, et al [33].…”

Temperature and host dependence of the transition interference between f–f and f–d transitions of Sm2+ in matlockites

“…The storage mechanism is based on the reduction of Sm 3 þ to Sm 2 þ upon exposure to ionizing radiation [15]. Recently, photoluminescence of Sm 2 þ /Sm 3 þ doped in Sr 4 Al 14 O 25 was studied [17]; also the luminescence of Sm 2 þ was used to monitor pressure induced phase transitions in BaBr 2 [18].…”

Strontium Aluminate-Based Long Afterglow PP Composites: Phosphorescence, Thermal, and Mechanical Characteristics

“…Recently, various phases of strontium aluminates with rare-earth-doped were developed, such as SrAl [18][19][20][21]. The wavelength of the emitted visible light is decided by the crystalline phase structure of the resultant strontium aluminate [22,23] [8,21,24].…”
