“…However, the above stated hypothesis has been confirmed in the case of wolframite-type ZnMoO 4 , which has E g = 3.22 eV [39]. A similar value is expected for MgMoO 4 , ruling out estimations that range from 4.5 to 5.5 eV [40]. On the other hand, the band-gap energy of 2.2 eV determined for NiMoO 4 [41] is fully consistent with the conclusions extracted from MnWO 4 .…”

Abstract:In this article, we review the advances that have been made on the understanding of the high-pressure (HP) structural, vibrational, and electronic properties of wolframite-type oxides since the first works in the early 1990s. Mainly tungstates, which are the best known wolframites, but also tantalates and niobates, with an isomorphic ambient-pressure wolframite structure, have been included in this review. Apart from estimating the bulk moduli of all known wolframites, the cation-oxygen bond distances and their change with pressure have been correlated with their compressibility. The composition variations of all wolframites have been employed to understand their different structural phase transitions to post-wolframite structures as a response to high pressure. The number of Raman modes and the changes in the band-gap energy have also been analyzed in the basis of these compositional differences. The reviewed results are relevant for both fundamental science and for the development of wolframites as scintillating detectors. The possible next research avenues of wolframites under compression have also been evaluated.

“…However the MgMoO 4 crystals with good quality were difficulty obtained because of the strong evaporation of MoO 3 component under high temperature [18], [19]. Therefore, in order to reduced the growth temperature we selected the top seeded solution growth (TSSG) method to grow the Cr 3+ ∶MgMoO 4 crystals.…”

“…Metal molybdates of the general formula AMoO 4 (A = Mg, Cd, Pb, Zn and Ca) have been attracted much attention owing to their important application of optoelectronic devices [13]–[16]. MgMoO 4 is a member of this family, it belongs to monoclinic system with C2/m space group and cell parameters a = 10.273, b = 9.288, c = 7.025, β = 106.96°, z = 8.…”

Recently, the MgMoO 4 and Yb 3+ -doped MgMoO 4 crystal were reported as a cryogenic phonon-scintillation detector [13]. The spectral properties of the Cr 3+ ∶MgMoO 4 crystal were reported such as crystal field strength and Racah parameters [17].…”

This paper reports the growth, mechanical, thermal and spectral properties of Cr3+∶MgMoO4 crystals. The Cr3+∶MgMoO4 crystals with dimensions up to 30 mm×18 mm×14 mm were obtained by TSSG method. The absorption cross-sections of 4A2→4T1 and 4A2→4T2 transitions are 12.94×10−20 cm2 at 493 nm and 7.89×10−20 cm2 at 705 nm for E//Ng, respectively. The Cr3+∶MgMoO4 crystal shows broad band emission extending from 750 nm to 1300 nm with peak at about 705 nm. The emission cross-section with FWHM of 188 nm is 119.88×10−20 cm2 at 963 nm for E//Ng. The investigated results showed that the Cr3+∶MgMoO4 crystal may be regarded as a potential tunable laser gain medium.
