Fabrication of quasi-metallic Ni_xMoO₃ nanodots for enhanced plasmon resonance and photothermal conversion

Abstract

The quasi-metallic NixMoO3 nanodots have been fabricated from semiconductive MoO3via SC CO2-assisted intercalation route, the introduction of Ni ion endows the NixMoO3 nanodots with enhanced plasmon effects and photothermal conversion efficiency.

Accurate Control of VS2 Nanosheets for Coexisting High Photoluminescence and Photothermal Conversion Efficiency

“…For instance, peculiar photoluminescence behavior has been observed in amorphous SnO 2 QDs quantum dots and wide‐band‐gap film such as Ta 2 O 5 , Ga 2 O 3 , BaTiO 3 , and SrTiO 3 , which is widely interpreted by the quantum confinement and structural disorder correlated defect level in amorphous structure. In particular, excellent photothermal performance in the visible and NIR regions caused by amorphous structure is also monitored in Ti x Ta 1− x S y O z nanosheets and Ni x MoO 3 nanodots …”

Accurate Control of VS2 Nanosheets for Coexisting High Photoluminescence and Photothermal Conversion Efficiency

“…[5] Forinstance, peculiar photoluminescence behavior has been observed in amorphous SnO 2 QDs quantum dots [6] and wide-band-gap film such as Ta 2 O 5 , [7] Ga 2 O 3 , [8] BaTiO 3 , [9] and SrTiO 3 , [10] which is widely interpreted by the quantum confinement and structural disorder correlated defect level in amorphous structure.I np articular, excellent photothermal performance in the visible and NIR regions caused by amorphous structure is also monitored in Ti x Ta 1Àx S y O z [11] nanosheets and Ni x MoO 3 nanodots. [12] Nowadays,h igh-quality transition metal dichalcogenides (TMDs) nanosheets,s uch as MS 2 (M = Mo,W )a nd MSe 2 (M = Mo,W )h ave been achieved on al arge scale through solution-phase methods. [13] Among of them, free-standing VS 2 with atomic thickness are predicted to have controllable electronic structure and intrinsic magnetic ordering.T odate, there are few reports to prepare the atomic-thick VS 2 nanosheets besides the restricted synthesis strategies including chemical vapor deposition (CVD) [14] and liquid-phase intercalation and exfoliation, [15] not to mention the corresponding 2D amorphous VS 2 .Based on the above discussion, it is desirable to develop af acile and general approach to realize the 2D crystalline-to-amorphous evolution of VS 2 and uncover its underlying optical phenomena.…”

Optothermal properties of plasmonic inorganic nanoparticles for photoacoustic applications

“…Nowadays, new compounds are extending the opportunities found in metal and semiconductor nanomaterials. Ni x MoO 3 nanodots, for example, display especially high PCE at 808 nm excitation, where many photoactive materials are tested [ 173 ].…”
