Mechanochemically assisted room temperature solid state metathesis reaction for the synthesis of MMoO4 (M = Ca, Sr and Ba)

Abstract

This communication reports a novel mechanochemically assisted room temperature solid state metathesis reaction for the synthesis of submicron-size alkaline-earth molybdates crystallizing in a tetragonal Scheelite structure. The solids were characterized by powder XRD, FTIR, TGA, DTA, SEM, EDAX and TEM to ascertain their composition, phase homogeneity and morphology.

Optical properties of Eu 3+ activated thorium molybdate and thorium tungstate: Structure, local symmetry and photophysical properties

“…4a and b is the expanded spectra from 350 to 575. platinum boat in an air atmosphere. XRD data of Th(MoO 4 ) 2 and Th (WO 4 ) 2 are comparable with those published earlier [10]. To study the optical properties of Eu doped thorium molybdates and tungstates, synthesis of Th(MoO 4 ) 2 and Th(WO 4 ) 2 doped with 2.0 mol% Eu was carried out by reacting ThO 2 , MoO 3 , WO 3 and Eu 2 O 3 in required molar proportions at 1073 K for 40 h.…”

“…Molybdates and tungstates are two important classes of inorganic compounds that have potential applications in various fields, such as hosts for lanthanide ions in solid state phosphors [2], lanthanide activated laser [3], luminescent materials [4,5], lithium ion batteries [6,7], microwave application [8] and catalysts [9,10].…”

A simple chemical method for the deposition of highly crystallized SrMoO4 films

“…Up to now, microcrystallites, submicronsize of SrMoO 4 have been studied extensively [2,3,7]. However, only limited investigations have been made on the preparation of the SrMoO 4 film and the high quality crystalline films may not be obtained by conventional method.…”

Calculation of Spectral Parameters for Doped/Codoped MWO4 (M = Ba2+/Ca2+) Phosphors

“…[1][2][3][4][5][6][7] These phosphors act as excellent hosts due to their important characteristics such as unique structure, high refractive index, low optical loss, high x-ray absorption coefficient, and good thermal/chemical stability. 8 These phosphors can be synthesized using a variety of methods, such as hydrothermal, spray pyrolysis, solid-state reaction, and combustion.…”
