Multi-dimensional architecture of Ag/α-Ag₂WO₄ crystals: insights into microstructural, morphological, and photoluminescence properties

Abstract

In this study, we report the potential of ethylenediamine (En) in the modification of the morphological, structural, optical and catalytic properties of α-Ag2WO4 crystals decorated with Ag nanoparticles (Ag NP)....

Bridging experiment and theory: Morphology, optical, electronic, and magnetic properties of MnWO4

“…A more intense right shift of the band is also observed with increasing MI approximately from 462 to 494 nm, in addition to the appearance of a new band at 646 nm in sample MnWO 4 -32. The displacement and formation of emission bands at longer wavelengths are due to the improved contributions of deep defects in the material, according to the broadband theory [48,58,59]. This emission is a result of the increase in the number of intermediate states close to the valence (VB) and conduction bands (CB), and may be related to the formation of oxygen vacancies (V O ) generated from the increase in the MI time of the MnWO 4 samples.…”

Strategies for the synthesis of complex oxides for application as light-responsive electrodes in photoelectrochemical cells – a review

“…However, these NPs can suffer Ostwald ripening, which implies the smaller particles precipitate onto larger ones, increasing the final particle size. 26 The choice of synthesis method will depend, mainly, on the final application and on the technical apparatus available.…”

Ag2WO4 as a multifunctional material: Fundamentals and progress of an extraordinarily versatile semiconductor

“…In 2020, the potential of ethylenediamine complexing agent to modulate the a-Ag 2 WO 4 morphology and structural properties was demonstrated, obtaining microflowers with favorable optical properties [114]. Additionally, the morphological evolution and antibacterial (against Staphylococcus aureus) and photocatalytic activity for degradation of RhB dye with a-Ag 2 WO 4 as catalyst obtained by the CP method followed by microwave irradiation for different times were also analyzed by our research group in 2020 [115].…”
