Ultrasonic-assisted Method for Preparation of Cu-doped ZnS Nanoparticles in Water as a Highly Efficient Visible Light Photocatalyst

Ultrasonic-assisted method was applied for preparation of Cu+2-doped ZnS nanoparticles (mole fractions of Cu+2 ions are 0.000, 0.015, 0.030 and 0.060) in water as a template-free and green method at 30 min. The prepared nanoparticles were investigated by powder X-ray diffraction (XRD), scanning electron microscopy (SEM), energy dispersive X-ray (EDX) and UV–Vis diffuse reflectance spectra (DRS)...

Colossal Magnetoresistance in Ce Doped Manganese Oxides

Highly efficient near-infrared quantum cutting in Ce

Near-infrared (NIR) quantum cutting involving the emission of two NIR photons for each visible photon absorbed is realized from Ce 3+ /Yb 3+ codoped chalcohalide glasses. Excitation, emission and decay spectra are measured to prove the occurrence of energy transfer (ET) from Ce 3+ to Yb 3+. The maximum ET efficiency obtained is as high as 82%, and the possible mechanism of ET is discussed. The ...

Photocatalytic Degradation of Methyl Orange by CeO2 and Fe–doped CeO2 Films under Visible Light Irradiation

Undoped CeO2 and 0.50-5.00 mol% Fe-doped CeO2 nanoparticles were prepared by a homogeneous precipitation combined with homogeneous/impreganation method, and applied as photocatalyst films prepared by a doctor blade technique. The superior photocatalytic performances of the Fe-doped CeO2 films, compared with undoped CeO2 films, was ascribed mainly to a decrease in band gap energy and an increase...
