Preparation and characterization of spray deposited NiMoO4 thin films for photovoltaic electrochemical studies

Structural, Optical, and Magnetic Properties of NiMoO4Nanorods Prepared by Microwave Sintering

“…UV-vis diffuse reflectance was used to determine the optical band gap energy of α , β -NiMoO 4 nanorods (for more details on this methodology see [17]). For our sample, the direct optical band gap presented a value of ~2.15 eV, which is in good agreement with values reported in the literature 2.3 eV [45]. The decrease in the band gap value can be attributed to defects and local bond distortion as well as intrinsic surface states and interfaces which yield localized electronic levels within the forbidden band gap [17].…”

Modulation of stoichiometry, morphology and composition of transition metal oxide nanostructures through hot wire chemical vapor deposition

“…Thus its ternary oxide can be either an nor p-type semiconductor depending on whether it is Ni or Mo enriched. The study of Pandey et al 44 showed NiMoO 4 to be an n-type semiconductor, while isostructural NiWO 4 has been reported to be p-type for films that are Ni rich and with its p-type conductivity decreasing with increasing W concentration. Thus, by tuning the composition, the band gap, doping, and charge carrier concentration of NiMoO 4 can be engineered to the desired specifications.…”

Shape‐Tailored Hydrothermal Synthesis of CdMoO4 Crystallites on Varying pH Conditions

“…Metal molybdates have a high application potential in various fields such as photoluminescence, microwave applications, optical fibers, scintillator materials, humidity sensors, and catalysis 4–9 . The numerous investigations on the synthesis of metal molybdates have been carried out 8–15 . Unfortunately, there are few reports on CdMoO 4 , especially on the investigation of its synthesis process 7,16 .…”

“…It is well known that luminescent properties of powders greatly depend on their particle size and morphology 20,12 . Although novel methods on the synthesis of metal molybdates with specific morphology 12–16 have been reported, there are still such limitations as needing higher calcined temperature and longer holding time to eliminate organic material or requiring complicated instrumentations and manipulations. Therefore, it is of significance to explore appropriate methods to synthesize metal molybdates and control their particle morphology and size under milder conditions.…”
