Optical, luminescence, and scintillation properties of advanced ZnWO4 crystal scintillators

Dark matter directionality approach using ZnWO$_4$ crystal scintillators

“…The ZnWO 4 crystals, developed by a single crystallization using a ZnWO 4 compound with the stoichiometric composition, with a deep purification of the WO 3 and implemented an annealed procedure in the air atmosphere of the crystal, have been shown the best crystals' optical transmission spectra in the range of 300-700 nm (see Ref. [29] for more details). Fig.…”

Synthesis, Characterization and Scintillation Response of ZnWO4-GO Nanocomposite

“…Hummer's method was applied to prepare graphene oxide [15][16][17][18]. To prepare ZnWO 4 by co-precipitation method, 0.01 mol.% of zinc acetate dihydrate (German Merck 99.99% purity) and sodium tungstate (Sigma Aldrich 99.99% purity) were used [18,19].…”

“…Due to their numerous uses in space exploration, non-intrusive security checks, and medical imaging these materials have development significantly in recent years [10][11][12][13][14]. Most commercial scintillators or ionizing ray detectors are in fragile crystal forms which have complex, time-consuming expensive preparation methods [15]. Various shapes of scintillators could be made from highly luminescent nanopowders such as flexible composite sensors in polymeric matrices [15][16][17].…”

“…Most commercial scintillators or ionizing ray detectors are in fragile crystal forms which have complex, time-consuming expensive preparation methods [15]. Various shapes of scintillators could be made from highly luminescent nanopowders such as flexible composite sensors in polymeric matrices [15][16][17]. For this aim here a straightforward procedure(co-precipitation) was chosen to synthesize the ZnWO 4 -graphene composite powders, which was then characterized using different techniques.…”

Construction of Z-Scheme Ag2MoO4/ZnWO4 Heterojunctions for Photocatalytically Removing Pollutants

“…During recent years, the semiconductor ZWO has been highlighted due to its many intersecting properties, such as dielectric, optical, thermal, scintillation, and luminescence properties. , The VB-edge position of ZWO is relatively low, signifying that the holes photoproduced in the VB tend to react with OH – or H 2 O to generate hydroxyl (·OH), which is a strong oxidant. This property suggests that ZWO is suitably used as a photocatalyst for the photocatalytic decomposition of organic pollutants. , Nevertheless, the easy recombination of photocarriers limits the photoactivity of bare ZWO and its practical application in contaminant elimination.…”
