Photoswitches of One-Dimensional Ag₂MO₄ (M = Cr, Mo, and W)

Abstract

Large-scale, high-purity, and uniform one-dimensional Ag 2 MO 4 (M ) Cr, Mo, and W) were obtained by a facile hydrothermal method. The as-prepared Ag 2 MO 4 materials exhibited linear current-voltage (I-V) characteristics and excellent photoresponse. As the light source was switched on and off, the currents could be reversibly switched between high and low value at the voltage of 0.1 V. Thus, the results suggested that the light-to dark-conductivity ratios of these compounds were correlated with the ionic potential of the metal. The extension of the photoresponses to silver silicate and silver vanadate also showed similar exciting results, indicating their potential applications in photoswitch devices in the future.

Low temperature micro Raman and laser induced upconversion and downconversion spectra of europium doped silver tungstate Ag2−3xEuxWO4 nanorods

“…A range of applications for silver tungstate is reported in the literature these include chemical fixation of CO 2 [22], a catalyst in organic chemistry [23], photoswitches [24], photocatalysis of organic pollutants [25][26][27][28][29][30], lubricants [31], electrocatalysis [32], gas sensor [33,34], LED [35] as well as an antimicrobial and antibacterial agents [36][37][38]. The influence of electron beam irradiation on structural and optical properties of this material has also been investigated [39].…”

Facile formation of Ag2WO4/AgX (X=Cl, Br, I) hybrid nanorods with enhanced visible-light-driven photoelectrochemical properties

“…As one of the most important metal tungstates, silver tungstate (Ag 2 WO 4 ) has three different crystallographic forms: a-, b-, and g-Ag 2 WO 4 , among which a-Ag 2 WO 4 is the thermodynamically stable phase that has been investigated [29,30]. To date, various synthetic routes, including controlled precipitation [31,32], hydrothermal [33][34][35], microwave-assisted [36], and injection method [37] were reported in the literature to obtain different Ag 2 WO 4 nanostructures. However, the preparation of metastable b-Ag 2 WO 4 has been scarcely reported [38].…”

Dissolvable Trimolybdate Nanowires as Ag Carriers for High-Efficiency Antimicrobial Applications

“…Here, we introduce a new kind of trimolybdate nanowires, namely Ag 2−x (NH 4 [34][35][36][37], the Ag 2−x (NH 4 ) x Mo 3 O 10 ·3H 2 O nanowires show strong antimicrobial properties, for example, they kill E. coli, Staphylococcus aureus, and unknown microbes in raw natural water with high efficiency. The nanowires are not dissolvable in deionized water; however they could be dissolved by the metabolic chemicals released from bacteria, making them attractive for many biological applications.…”
