“…A SrWO 4 single crystal was successfully synthesized using the Czochralski pulling method. 114 Luminescence spectrum under X-ray excitation of a bulk SrWO 4 single crystal was observed to show a broad emission band from 300 to 700 nm at room temperature. The decay time spectrum was reported to contain two components of 2.6 ns (5.7%) and 522 ns (94.3%) at room temperature.…”

“…The LTbH:Gd was also observed to have multiple roles, including energy-transfer bridges that connect the sensitizers and Tb 3+ (in host) to enhance the characteristic emission of Tb 3+ and the phosphorescence of sensitizers, while also act as host matrixes for the sensitizers. A SrWO 4 single crystal was successfully synthesized using the Czochralski pulling method . Luminescence spectrum under X-ray excitation of a bulk SrWO 4 single crystal was observed to show a broad emission band from 300 to 700 nm at room temperature.…”

“…These broad features are attributed to intrinsic oxygen to tungsten charge transfer transition within the WO 4 2À group which has been reported by many authors. 7,10,[17][18][19][20][21][22][23][24] The interesting feature is the evident red shi of this peak in the nano domain. The peak shi is non-monotonous possibly due to distributions in the nanoparticle sizes.…”

“…Among divalent tungstates, strontium tungstate scores over others because of its unique scintillation properties even at low temperatures and ability to act as a host wherein both laser as well as Raman properties can be exploited together. 6 It also has other important applications as optical sensor, 6 scintillator, 7 laser host 8 etc. SrWO 4 belongs to scheelite family having tetragonal structure with space group I4 1 /a and point group symmetry C 4h 6 .…”

“…There are quite a few reports on photoluminescence properties of pure 7,10,[17][18][19][20][21][22][23][24] and europium doped 10,[25][26][27][28][29][30] sample. But none of these works systematically explain the effect of annealing temperature on optical properties of pure and europium doped SrWO 4 .…”
Effect of annealing temperature on photophysical characteristics of pure and SrWO4:Eu3+ nanoparticles were investigated and the changes observed correlated with density function theory (DFT) and positron annihilation lifetime spectroscopy (PALS).
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
