Morphological control of PbWO4 crystals in the ethanol–water mixed system with an anionic surfactant

Enhanced visible-light-driven photocatalytic performance for degradation of organic contaminants using PbWO4 nanostructure fabricated by a new, simple and green sonochemical approach

“…Lead tungstate has aroused very notable interest due to its wide range of uses in scintillators, amplifiers, photocatalysis and lasers [9] , [10] . Lead tungstate structures have been prepared applying various approaches such as co-precipitation, hydrothermal, solid-state reaction and Bridgman route [11] , [12] , [13] , [14] . Today, the sonochemical pathway is applied as a helpful synthesis procedure to create a range of nanoscale compounds with various shapes [15] , [16] , [17] .…”

Hydrothermal synthesis and electronic properties of FeWO4 and CoWO4 nanostructures

“…The tungstates continue attracting considerable attention because they are found to be a fascinating family of materials possessing various technological applications such as microwave, scintillation, optical modulation, magnetic and writing-reading-creasing devices, humidity sensors, optical fibers and photoluminescence materials [3,4]. Therefore, many tungstates such as MWO 4 (M = Mn, Fe, Co, Ni and Cu) [5], MnWO 4 [6,7,8], FeWO 4 [1,3,7], CoWO 4 [2,9], NiWO 4 [7,10,11], CuWO 4 [12,13], ZnWO 4 [7,11,14] and CdWO 4 [15] with a wolframite-type structure as well as CaWO 4 [7,16], AWO 4 (A = Ca, Sr) [17], SrWO 4 [7,18,19], SnWO 4 [20,21], BaWO 4 [7,22,23] and PbWO 4 [4,[24][25][26][27] with a scheelite-type structure have been synthesized employing various novel methods, which allow to obtain well-defined and high-pure materials, mainly nanosize tungstates.…”

Synthesis and photoluminescence improvement of monodispersed Zn2SiO4:Mn2+ nanophosphors

“…Our approach is capable of making the nanoparticles without agglomeration via surfactant molecules assisted hydrothermal process. The surfactant molecules adsorb on the surface of particles and stabilize the particle against agglomeration by either electrostatic repulsion or steric force [24,25]. After post heat treated at 1300 • C, these Zn 2 SiO 4 :Mn 2+ nanophosphors keep the spherical shape, fine particle size and monodispersed characteristics as shown in Fig.…”
