Atomically Flat

The processes for polishing a ZnO surface were investigated with the aim of establishing a process for obtaining an atomically flat surface with high crystalline quality. The defects in a layer undergoing mechanical polishing were monitored through photoluminescence measurements, and the purity of the polished surface was characterized by SIMS. An atomicallyfishing process.

In this paper, ZnWO4: La3+, Y3+ photocatalysts were synthesized by a high-temperature solid state reaction method. The effects of La3+ and Y3+ doping contents on the phase, morphologies and optical properties of the samples were characterized by X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), Diffuse reflectance spectra (DRS), photoluminescence spectra (PL), Raman and UV-visible spectroscopy, respectively. The as-prepared ZnWO4:La3+, Y3+ photocatalysts showed photoluminescence with a broad band emission, and high photocatalytic activity in degradation of rhodamine B (RhB) under simulated UV irradiation. The results showed that co-doping in ZnWO4 can enhance light harvesting capability to generate more electron-hole pairs, and acted as a trap center by decreasing the recombination of photogenerated electrons and holes. All the results obtained by the work suggest that ZnWO4: La3+, Y3+ photocatalysts are promising materials for the photocatalytic decomposition of pollutants.
