Novel Sm3+ doped columbite-type orthorhombic structured MgNb2O6 (MNO) orange-red emitting phosphors were prepared by solution combustion method using ODH as a fuel. The powder phase purity, particle morphology, size, elemental composition, luminescence properties, photocatalytic behaviors and electrochemical studies of prepared samples were studied in detail. Photoluminescence emission spectra of MNO:Sm3+ nanophosphors show all the characteristic emissions of Sm3+ cations corresponds to the transitions 4G5/2 → 6Hj/2(j=5,7,9,11) when excited at 463 nm energy. Among these the strongest emission peak was at 608 nm which corresponds to 4G5/2 → 6H7/2 transition of Sm3+ cations in the host lattice. The luminescence quenching was confirmed by the dipole–dipole interaction among Sm3+ ions. As a result of J-O analysis the branching ratio (~ 58% > 50%) show that the phosphor was highly suitable for color display devices. Photocatalytic activity of MNO:Sm3+ (5 mol%) under UV light shows 99% degradation of AR-88 dye. Electrochemical Impedance Spectroscopy (EIS) confirms the reversibility of the redox reaction, which helps in sensing the presence of paracetamol and alcohol. Thus, MNO:Sm3+ phosphors have great potential applications in display, catalytic, photonic, chemical and thermal sensor applications.

“…23 Metal molybdates, in particular, exert a synergistic action of a combination of metals and molybdates, resulting in improved conductivity and stability, which is required for effective energy storage. 24 Bismuth molybdates, members of the Aurivillius-related oxide family, one of the important semiconducting materials having the general formula Bi 2 O 3 •nMoO 3 , where n = 1 to 3, comprise perovskite-like (MoO 4 ) 2− and fluorite-like (Bi 2 O 2 ) 2+ slabs arranged alternately. The three different phases of bismuth molybdates, α-Bi 2 Mo 3 O 12 , β-Bi 2 Mo 2 O 9 , and γ-Bi 2 MoO 6 , differ in their crystal structures and elemental compositions.…”

“…However, there are still many pending issues for metal molybdates due to their large volume changes and low conductivity. Tremendous effort has been devoted to solving these problems by combining molybdates and various carbon materials, such as amorphous carbon, carbon nanotubes, carbon fabric and reduced graphene oxide [29][30][31][32].…”

Metal molybdates have attracted considerable attention as promising anode materials for sodium ion batteries (SIBs) due to their high theoretical specific capacity and excellent electrochemical performance. However, their low rate capacity and rapid capacity attenuation hinder their application in SIBs. Here, amorphous NiMoO4/graphene nanofibers were prepared via an electrospinning method. The electrochemical performance of NiMoO4 was first reported as the anode for SIBs. Amazingly, the amorphous NiMoO4/graphene delivered an outstanding specific capacity of 260 mAh g−1 after 100 cycles at 100 mA g−1 at a potential range from 0.01–2.7 V and an excellent rate performance of 160 mAh g−1 at 1 A g−1. The superior electrochemical properties of amorphous NiMoO4 can be ascribed to its amorphous structure and reduced diffusion distance, and the strong synergy of NiMoO4 and graphene.
