“…In the past few decades, PbMO 4 (M = Mo, W) crystals have been prepared mainly by solid-state reaction , and Czochralski crystal growth. − Nevertheless, the preparation of this material usually requires complicated experimental procedures, sophisticated equipment, and rigorous synthesis conditions. Thus, recently, wet chemical synthesis causes great attention in the synthesis of micro- and nano-PbWO 4 crystals.…”

Large-scale selective synthesis of uniform microcrystals lead tungstate (PbWO 4 ) with controlled morphologies has been achieved via a facile surfactant-assisted hydrothermal process. The formation of PbWO 4 crystal is strongly dependent on its reaction parameters. The variation of different types of surfactants (such as P123, cetyltrimethyl ammonium bromide (CTAB), poly (vinyl pyrrolidone) (PVP), and dodecyl benzene sulfonic acid sodium salt (SDBS), respectively), reaction temperature, and reaction time are found to play a crucial role in controlling the particle size and morphology of the products. The growth process has been investigated by carefully following time-dependent experiments, and the oriented attachment process has been proposed for the possible formation mechanism. The optical properties, such as UV-vis spectra and PL spectra of PbWO 4 crystals, were studied and the room-temperature photoluminescence of PbWO 4 samples with different morphologies was investigated.

“…Li + doping enhances the luminescence of PWO and gives some contribution to the “fast” decay components. Recently, Zorenko et al 10 arrived at a similar conclusion in PWO:Li 2 CO 3 , i.e., that Li + leads to increased luminescence of PWO(O 2 ) (grown in O 2 atmosphere) and to a decrease of the “slowest” component contribution from 5.5% down to 3.8% 10.…”

Lithium‐doped PbWO4 crystals have been grown by the Czochralski method. Optical absorbance, X‐ray excited luminescence, light yield measurements and X‐ray pulsed excited decays have been investigated. Li+ doping has a very good uniformity and could enhance the luminescence of PbWO4, give some contributions to the “fast” decay components. (© 2004 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)

“…Figure 3 presents the PL spectra of the all doped PWO. The PL spectrum of pure PWO consists of at least three noticeable peaks with maxima at about 420-440, 490, and 590 nm, [14,15] which are assigned to self-trapped excited blue and blue-green luminescence arising from the [WO 4 ] 2− complexions respectively. [16] For PWO:Y:Zn crystals, the intensity of blue luminescence is enhanced with the increasing doping of Zn ions.…”

Zn and RE (RE = La, Yb, Y) ions co-doped PbWO4 (PWO) single crystal grown by the Czochralski technique are characterized by x-ray diffraction (XRD), optical transmission spectra, and photoluminescence (PL). The doping of Zn ions shows distinct effects on the properties of PWO:RE crystals. At low concentration of Zn ions (200 ppm), the luminescence intensity is quite weak for (Zn,La)-doped PWO, but is substantially strong for (Zn,Yb)-doped PWO. The blue luminescence intensity is significantly enhanced with the increasing Zn ions doping for PWO:Y. The trivalent ions codoping can increase the ratio of the blue luminescence contributing to the fast components of light yield. Yb ions can enhance efficiency of luminescence in PWO:Yb:Zn because they may act as a luminous sensitization agent which can be involved in the efficient energy transfer and storage of the radiative process.
