چکیده
|
The rare earth couple ytterbium-erbium doped tin dioxide (sno2:yb3+/er3+) were prepared by sol gel method using tin(ii) chloride as source of sn2+ ions,ytterbium and erbium chloride hydrate for doping rare earth ions source. this material is considered as a promising up-converter material for solar cell due to energy transfer (etu) between the rare earth dopant elements. the powders of pure and doped samples were prepared and characterized by x-ray diffraction drx,infrared spectroscopy atr-ftir,x-ray fluorescence rfx techniques. the inductively coupled plasma icp-ms were performed for elemental composition. all the results are shown and discussed. rfx and icp-ms exhibits a ratio of 10 between the dopant's concentrations. © 2017,university of mohammed v rabat morocco.
