Influence of Sb and Y co-doping on properties of PbWO4 crystal

Structural, photocatalytic and electroconductive properties of bismuth-substituted CaMoO4

“…Mechanism ( 1) is reported for La doped PbWO 4 [8] and PbMoO 4 [9], as well as Sm doped CaMoO 4 [10], mechanism (2a) for Li, Sm co-doped CaWO 4 [11] and mechanism (2b) for Y, Sb codoped PbWO 4 [12], with mechanism (3) in rare-earth substituted Ca(Mo/W)O 4 , Sr(Mo/W)O 4 and Cd(Mo/W)O 4 [13][14][15]. Cation vacancies (Ф) and their ordering can have important consequences, not only on structure, but also on the physical and chemical properties.…”

Antimony(III)-Doped PbWO4 Crystals with Enhanced Photoluminescence via a Shape-Controlled Sonochemical Route

“…14 However, as reported previously, the green component of PbWO 4 crystals is slower than the blue one in the decay characteristics. 46 Sbdoping can enhance the intensity of luminescence but may give some contributions to the "slow" decay components 16 which may be negative to the scintillating properties of PWO. Further detailed investigation is needed.…”

“…Sb-doped PbWO 4 single crystals have usually been grown from the melt using the Czochralski , and Bridgeman − methods. To the best of our knowledge, the wet-chemical synthesis of doped PbWO 4 has not been reported, especially with controlled shapes.…”

“…Sb-doped PbWO 4 (PbWO 4 :Sb) does show greater transmittance and radiation hardness, as well as better luminescence intensity and light yield. 10,11 Sb-doped PbWO 4 single crystals have usually been grown from the melt using the Czochralski 12,13 and Bridgeman [14][15][16] methods. To the best of our knowledge, the wet-chemical synthesis of doped PbWO 4 has not been reported, especially with controlled shapes.…”

Photo- and thermally stimulated luminescence of non-stoichiometric undoped PbWO4crystals

“…There are new ideas about the coloration, i.e., radiation damage mechanism in PbWO 4 24. To further increase the light yield, the continued attention is paid to doubly doped PbWO 4 25, 26. It is also worth mentioning that another technologic ways of PbWO 4 preparation were tempted, namely in the nanocrystal 27, 28 and thin film 29 forms which can provide further insight in the optical and luminescence characteristics of PbWO 4 .…”
