Electrical and humidity sensing properties of lead(II) tungstate–tungsten(VI) oxide and zinc(II) tungstate–tungsten(VI) oxide composites

Synthesis, growth process and photoluminescence properties of SrWO4 powders

“…In this type of structure, the B ions are within tetrahedral O-ion cages and isolated from each other, while the A ions are surrounded by eight oxygens [6,7]. Currently, these materials have been widely employed in several industrial applications, such as: optic fiber, humidity sensor, catalysts, scintillation detector, solid-state lasers, photoluminescent devices, photocatalysts, microwave applications and more [8][9][10][11][12][13][14][15][16]. In particular, SrWO 4 has attracted considerable attention to the development of new electrooptics devices due to its blue or green luminescence emissions at room temperature [17,18].…”

Electrolytic sensor for trace level determination of moisture in gas streams

“…doi:10.1016/j.measurement.2010.09.023 moisture standards and low level moisture generation systems are not readily available [16] because of the speculation involved in the measurement. P 2 O 5 has been used as 5% moisture standard in many humidity sensor literature [17][18][19]. The present study addresses the disadvantages experienced by earlier studies while designing a trace level moisture sensor in inert gas streams.…”

Synthesis and characterization of barium molybdate nanostructures with the aid of amino acids and investigation of its photocatalytic degradation of methyl orange

“…Especially, because of the increasing need for high area density storage, the synthesis and characterization of semiconductor nanocrystals have been extensively investigated [4][5][6][7][8]. In recent years, tungstates and molybdates are materials that have attracted the interest of many researchers due to their broad potential to industrial application including optic fiber, humidity sensor, catalysts, scintillation detector, solid-state lasers, photoluminescent devices, microwave applications, and so on [8][9][10][11][12][13][14][15][16][17][18][19][20][21][22]. Molybdates and tungstates are significant luminescent materials with scheelite-type tetragonal structure, membership I41/a space group with two formula units per primitive cell.…”
