Abstract
AgBiS 2 nanoparticles (NPs) have been loaded on multiwalled carbon nanotubes (MWCNTs) by the solvothermal treatment on a mixture of MWCNTs, AgNO 3 , Bi(NO 3 ) 3 ·5H 2 O and thiosemicarbazide in a mixed polyol solvent. The resulting MWCNT-AgBiS 2 hybrid samples have been extensively characterized by a variety of microscopic and spectroscopic techniques. The AgBiS 2 NPs can be uniformly deposited on the sidewalls of MWCNTs by appropriately regulating the reaction conditions including reaction temperature and reaction time. Optical limiting (OL) studies have been performed on typical MWCNT-AgBiS 2 samples using the Z-scan and OL measurements at the laser wavelength of 532 nm. The MWCNT-AgBiS 2 hybrids with AgBiS 2 NPs of ∼16 nm in size uniformly coated on the nanotubes show a significantly enhanced OL effect in comparison to the purified MWCNTs.
