Dielectric, optical and EPR studies of PbMoO4 single crystals, pure and doped with cobalt ions

Spin Hamiltonian Parameters for Co2+Ions in PbMoO4Crystal - Interplay between the Fictitious Spin S'=1/2 and the Effective Spin S̃ =3/2

“…Concerning the orientation of the principal axes of the g-tensor for the complexes Co 2+ (α) with respect to the crystallographic axes (a, b, c) in PbMoO 4 crystal, we follow the definitions outlined in [19,22]. The results [19] correlate well with interpretations of earlier optical measurements [22], thus suggesting that Co 2+ ions substitute at the Mo 6+ tetrahedral sites. The g i values [19] are very close to the principal g i values determined for Co 2+ in PbWO 4 crystals by Chen and Artman [17,18].…”

Toward Understanding the Photocatalytic Activity of PbMoO4Powders with Predominant (111), (100), (011), and (110) Facets. A Combined Experimental and Theoretical Study

“…As an important member of this family, lead molybdate (PbMoO 4 ) has gained increasing interest due to its use in a wide range of technological and theoretical fields 12, [14][15][16][17][18][19][20][21][22][23][24] , and experimental studies on the optical properties of lead molybdate have been published by different research groups. 16,19,[25][26][27][28][29][30][31][32][33][34] PbMoO 4 crystallizes in tetragonal scheelite-structure having point group symmetry 4/m and space group I41/a, with two formula units per primitive cell. 5,6 , and a specific feature of these systems is the existence of two different clusters into crystal lattice, in which each Mo is surrounded by four equivalent O atoms composing the ሾMoO ସ ሿ ଶି tetrahedral configuration and each divalent metal, Pb, shares corners with eight adjacent O atoms, forming a ሾPbO ଼ ሿ ଶି configuration.…”

Synthesis of lead molybdate and lead tungstate via microwave irradiation method

“…Among them, lead molybdate (PbMoO 4 ) and lead tungstate (PbWO 4 ) are very attractive materials. PbMoO 4 have recently gained increasing attracting interest as possible acousto-optical materials, because of their applications as acousto-optical deflectors, modulators, ion conductors and their great potential to act as effective lowtemperature scintillators in nuclear instruments [4,5]. PbWO 4 is a good candidate in radiation detection in high-energy physics and nuclear physics due to its high density (8.3 g/cm 3 ), short radiation length (less than 10 ns for a large part of light output), small Moliere radius, fast decay time, non-hygroscopicity and low production cost [6][7][8].…”
