The crystalline structure, morphology, and optical properties of Cu_2MoS_4 nanoparticles were characterized using X-ray diffraction, X-ray photoelectron spectroscopy, field emission scanning electron microscopy, and UV-vis spectrophotometry. Cu_2MoS_4 nanoparticles having a band gap of 1.66 eV exhibits good photocatalytic activity in the degradation of methylene blue, which indicates that this simple process may be critical to facilitate the cheap production of photocatalysts.展开更多

A self-focusing property for the solution of MoS4Cu4(SCN)2(NC5H5 )6 in DMF was observed. The nonlinear refractive index was n2=3.1×10-14 cm2·W-1. Compairing with early results, this sample showed a self-defocusing property at the same wavelength by using 7 ns laser pulse. The optical limiting properity was also studied by using same condition.展开更多
