Structural, morphological and photoluminescence properties of β-Ag2MoO4 doped with Eu3+

Rietveld Refinement, Morphology, and Optical and Photoluminescence Properties of a β-Ag1.94Cu0.06MoO4 Solid Solution

“…The normalized intensities are different, suggesting replacement of the Cu 2+ ions. [1][2][3]5 3.3. UV−Vis by DRS.…”

“…The Rietveld refinement method was performed using the diffraction patterns of the β-Ag 2 MoO 4 and β-Ag 1.94 Cu 0.06 MoO 4 samples as the input file. − Also, the structural information from COD 7222296 (.cif) was used as the theoretical data. This study used the Fullprof program (public domain), July 2021 version for Windows, to compute the experimental and theoretical data.…”

“…11−13 Silver molybdate (Ag 2 MoO 4 ) is an important member of this family and has two polymorphs: α-Ag 2 MoO 4 with a tetragonal structure and α-Ag 2 MoO 4 , which exhibits a cubic spinel-like structure. 2,8,14 Therefore, stick, 15 flower, 16 and potato 17 morphologies have been synthesized for these materials. β-Ag 2 MoO 4 has aroused great interest because of its good chemical stability at high temperatures, in addition to presenting a range of applications in different fields including energy storage, 18 antimicrobial agents, 1,2 photocatalysis, 19,20 and PL.…”

“…4,5 For this reason, the insertion of dopants on these materials such as rare-earth metals have been extensively studied. 2 Although the rare-earth metals are attractive candidates as dopants, a reduction in the availability coupled with demand has led to increased prices for these compounds. Consequently, other metals such as zinc (Zn), 3 cobalt (Co), 23 bismuth (Bi), 24 and copper (Cu) 25 were studied as an alternative dopant.…”

“…Molybdenum oxide compounds are a well-known semiconductor family that has been investigated for several applications such as catalysts, − sensors, , photocatalysts, , microbial agents, , and photoluminescence (PL). − Silver molybdate (Ag 2 MoO 4 ) is an important member of this family and has two polymorphs: α-Ag 2 MoO 4 with a tetragonal structure and α-Ag 2 MoO 4 , which exhibits a cubic spinel-like structure. ,, Therefore, stick, flower, and potato morphologies have been synthesized for these materials. β-Ag 2 MoO 4 has aroused great interest because of its good chemical stability at high temperatures, in addition to presenting a range of applications in different fields including energy storage, antimicrobial agents, , photocatalysis, , and PL. , However, β-Ag 2 MoO 4 has an effective photon absorption in the ultraviolet region, which is limited to several photonics applications. , For this reason, the insertion of dopants on these materials such as rare-earth metals have been extensively studied . Although the rare-earth metals are attractive candidates as dopants, a reduction in the availability coupled with demand has led to increased prices for these compounds.…”
