“…4 indicates optical absorption peaks in the range of 200 nm to 600 nm of pure and Ni doped ZnO NPs. The absorption peaks of these NPs were observed in range 375-391nm.With addition of Ni dopant agent these peaks shifted towards longer wavelength (red shift) [21].…”

In this work, Zn1-xNixO NPs with different concentration (x= 0.0, 0.03, 0.06 and 0.09) were synthesized by using co-precipitation method. The present study is related to investigate crystal structure, surface morphology, optical and magnetic behavior of pure and Ni dopant ZnO NPs. The hexagonal wurtzite structure and crystallite size (19.45 to 21.25 nm) was investigated by using XRD analysis.SEM and FTIR used to identify the surface morphology, stretching and vibrational modes of different functional groups (ZnO, OH, CO and H-O-H) attached on the spectrum of Ni dopant ZnO NPs. Moreover, the optical behavior of Ni dopant ZnO NPs was studied by UV-visible spectroscopy which indicates the absorption band of red shift. Finally, VSM analysis illustrated that Ni dopant ZnO NPs shows high magnetization, retentivity and low corecivity as compare to pure ZnO NPs. In an overall assessment the Ni dopant ZnO NPs shows better optical and magnetic properties for biomedical applications.

“…Để tăng cường tính ổn định và hoạt tính xúc tác quang hóa, ZnO thường được pha tạp, hybrid hoặc composite với kim loại, phi kim hoặc oxit bán dẫn vùng cấm hẹp ]5 -9]. Kim loại chuyển tiếp là một trong những nhóm kim loại thường được sử dụng pha tạp với ZnO [10,11,12]. Giữa các kim loại chuyển tiếp đó, đồng là một trong những kim loại chuyển tiếp quan trọng để pha tạp vì một số tính chất đặc biệt như điện, quang và từ.…”

Cuprous oxide nanoparticles (Cu2O) were prepared by a one-step reduction method at 65, 70 and 85oC temperature. The Cu2O nanoparticles were characterized by XRD, Raman, SEM and EDS techniques, respectively. The adsorption removal of red congo dye from aqueous solution by the as-prepared Cu2O nanoparticles was studied. Kinetics and isotherms studies suggested that the adsorption process followed pseudo-second-order and Freundlich models. The maximum adsorption capacity was estimated to be 82,6 mg/g, which was the highest reported value so far for red congo adsorption.

“…However, the trade-off is a reduction in the band gap e.g. to as low as ∼3.15 (6% Ni) from ∼3.37 eV (undoped) [13] , [14] . By the foregoing arguments, the distribution of interface states is also enhanced with new carrier valleys introduced in the band gap.…”
