Study on preparation and characterization of uniform bismuth nanospheres
Nianjing Ji,Ziqing Li,Yang Chen,Jiyang Wang,Xiulan Duan,Huaidong Jiang 한양대학교 세라믹연구소 2018 Journal of Ceramic Processing Research Vol.19 No.5
The uniform and monodisperse bismuth nanospheres were successfully prepared by simple and convenient solvothermalmethod. The bismuth nitrate was reduced by ethylene glycol at 150-200 oC for 20-30 hrs. The nanospheres were characterizedby powder X-ray diffraction, scanning electron microscopy and transmission electron microscopy. The dispersivity of bismuthnanospheres was investigated using optical microscope. The optimum reaction conditions to prepare the uniform bismuthnanospheres with a narrow diameter range was investigated. The results indicate that the monodisperse bismuth nanospheresprepared at 200 oC possess sizes ranging from 100-200 nm. The formation mechanism of the bismuth nanospheres washypothesized.

Phases and morphorlogy of CuFeS2 films prepared by electrodeposition
Ming Ji,Kegao Liu,Nianjing Ji 한양대학교 세라믹연구소 2020 Journal of Ceramic Processing Research Vol.21 No.4
This work reports one low-priced ways for production of CuFeS2 films on conductive glass surface. CuFeS2 films wereprepared by electrodeposition and post-sulfurization treatment at 220 oC for 30 h in N2 atmosphere for the first time. CuFeS2films were prepared by electrodeposition with sulfate, ascorbic acid, complexing agent sodium citrate as raw materials. Whenthe deposition potential is -1.0 V and the deposition time is 20 min, CuFeS2 thin films with good phrase formation can beobtained at pH 4 and 0.02M Na2S2O3·H2O. The phase of samples were characterized using X-ray diffraction (XRD). Themorphology of samples were characterized via scanning electron microscopy (SEM). The composition of samples werecharacterized by energy dispersive spectrometer (EDS). The crystallinity of CuFeS2 thin films prepared under these conditionsare relatively good. The microcosmic morphology of the samples is flaky crystal. It is shows that post-sulfurization method ishelpful for the phase formation of CuFeS2 films electrodeposited.
