Tb3+/Pr3+ co-doped ZnMoO4 phosphor with tunable photoluminescence and energy transfer processes

Facile synthesis of ZnMoO4/AlPO4-5 nanorod composites as visible-light-driven photocatalysts and high-performance energy storage materials

“…Additionally, the presence of ZnMoO 4 in MZ/AlPO 4 -5 catalysts results in AlPO 4 lattice distortion, altering the interplanar distances within their crystal lattices. 30 This result ultimately promotes good crystallinity and optical properties necessary for effective degradation/activity.…”

“…Thus, using the F ( R ) function in conjunction with the Tauc eqn (4) , the spacing between the conduction band and the valence band of the synthesized material was estimated as follows: ( αhv ) = ( hv − E g ) n where α is absorption coefficient directly proportional to F ( R ), hv and E g are photon energy and optical band gap energy, respectively, and n equals 1/2 because ZnMoO 4 is an indirect gap semiconductor. 30 …”

“…It is an inorganic substance found in nature with two distinct crystalline phases: a-triclinic and b-monoclinic. 11 Zinc atoms (Zn) are bound to six oxygen atoms (O), forming distorted octahedral clusters [ZnO 6 ]; zinc and molybdenum atoms are bound to six O atoms which encourage the origin of distorted octahedral clusters [ZnO 6 ]/[MoO 6 ]. 12,13 The photoactivity of ZnMoO 4 is a result of its structural diversity, superior optical properties in a broad emission spectrum, and substantial charge transfer between the bands of activated 2p (O 2 ) and 4d (Mo 6+ ) orbitals.…”

Growth mechanism and vibrational and optical properties of SrMoO4: Tb3+, Sm3+ particles: green–orange tunable color

“…Luminescence of a rare-earth ion from the use of a sensitizer (S) will be higher compared to direct activation of the activator (A) due to the energy transfer being favorable to the activator, and further improvements in intensity can be achieved by combining (S) and (A) [5,6]. According to Pavani et al [7], the choice of host material to be used must be made carefully to meet the appropriate requirements for the use of optical devices.…”

Synthesis and characterization of BaWO4:xTm3+,yPr3+ obtained by ultrasonic spray pyrolysis

“…Thus, numerous studies are realized to create or to improve materials with photocatalytic properties using several methods of synthesis and/or different doping. Ahmad et al [18], Ping and Wang [19], and Lovisa et al [20] utilized Pr +3 as a dopant of ZnO, TiO 2 and ZnMoO 4 , respectively, and observed an increase of photocatalytic activity of Pr +3 -doped matrix compared to the undoped material in the methylene blue discoloration. However, Lu et al [21] and Mazierski et al [22] synthesized Pr +3 -doped TiO 2 and analyzed that the doping favored the photocatalytic process in the methylene blue and phenol degradation, respectively.…”
