Atomistic Perspective on the Intrinsic White-Light Photoluminescence of Rare-Earth Free MgMoO4 Nanoparticles

“…An alternative approach to attain single-component white-light photoluminescent material consists of combining distinct synthesis routes and their experimental parameters to obtain structural and morphological modifiers that govern the main photoluminescence properties of rare-earth free materials. − For instance, we recently obtained Mg 1– x Sr x MoO 4 ( x = 0, 0.25, 0.50, 0.75, and 1) powders from the ultrasonic spray pyrolysis (USP) method, which displays neutral- and cool-white emission with high-quality white light (CRI > 80%) . Indeed, magnesium molybdate (MgMoO 4 ) has attracted scientific interest because of its interesting properties that enable applications such as luminescence, lithium-ion batteries, lasers, and catalysts, among others. − In particular, some authors have confirmed that shape-oriented MgMoO 4 nanoparticles can exhibit tailored properties and result in superior applications. ,, …”

“…Despite scientific efforts devoted to investigating MgMoO 4 properties, a detailed analysis of surface exposure and morphological modulations for these materials remains challenging from both theoretical and experimental points of view. Indeed, only a few MgMoO 4 nanostructures have been reported so far, such as particle, fibrous, nanosheet, and plate-like morphologies. Therefore, the design and synthesis of shape-oriented MgMoO 4 nanomaterial still present a great challenge.…”

“…26−31 In particular, some authors have confirmed that shape-oriented MgMoO 4 nanoparticles can exhibit tailored properties and result in superior applications. 28,29,32 MgMoO 4 can be obtained as α or β, depending on the temperature and pressure. α-MgMoO 4 crystallizes in a cuproscheelite-type structure (P1̅ ) but is only stable at high pressures.…”

New insights into the electrochemistry of magnesium molybdate hierarchical architectures for high performance sodium devices

“…Overall, the shape of the subsequent discharge and charge curves are almost identical in the second and fifth cycles, though the discharge curves are not exactly superimposable as charge process. This minor discrepancy could be attributed to the stabilization process of the electrode that depends on the quality of the solid electrolyte interphase (SEI) layer formed on the surface 32. The electrochemistry of the redox mechanism and the formation of materials formed in sodium-ion batteries for molybdates are not well proposed in the literature yet.The storage and cycling properties of MgMoO4 were investigated by galvanostatic cycling with the voltage window 0.005 -2.5 V vs. Na at a current of C/10 rate and the profiles are shown in Fig.…”

Spray pyrolysis synthesis and characterization of Mg1-xSrxMoO4 heterostructure with white light emission

“…Silva et al [68] and Zhu et al [45] synthesized SrMoO 4 and obtained band gap values between 4.17 and 4.36 eV (agglomerates particles by complexation) and between 3.81 and 2.71 eV (nanoparticles by thermal decomposition), respectively. Wannapop et al [69] and Zhang et al [70] produced MgMoO 4 and estimated the band gap value of 5.15 eV (fibers via electrospinning) and between 3.72 and 3.78 eV (nano-flowers and nanosheets via self-assembly), respectively.…”
