چکیده
|
In current work, new hybrid composite have been prepared by mixing gold nanocolloid physically with pva-fe2o3. morphological, compositional, structure and optical properties of hybrid composites were studied by transmission electron microscope (tem), scanning electron microscope (sem), energy dispersive spectroscopy (eds), fourier transform infrared spectroscopy (ftir), x-ray diffraction (xrd) and uv-visible spectroscopy (uv-vis). xrd results showed that both au and fe2o3 have peaks in the structure and that confirmed by eds and ftir results. microscopes results indicated the nanosized nature of prepared materials. uv–vis spectrum show absorption edge at 440 nm which relates to pva-fe2o3 mixed with au which means there is a red shift after incorporation of au in the composites. and the energy gap of composite became equal to 2.48 ev after adding au solution.

Abstract

in current work, new hybrid composite have been prepared by mixing gold nanocolloid physically with pva-fe2o3. morphological, compositional, structure and optical properties of hybrid composites were studied by transmission electron microscope (tem), scanning electron microscope (sem), energy dispersive spectroscopy (eds), fourier transform infrared spectroscopy (ftir), x-ray diffraction (xrd) and uv-visible spectroscopy (uv-vis). xrd results showed that both au and fe2o3 have peaks in the structure and that confirmed by eds and ftir results. microscopes results indicated the nanosized nature of prepared materials. uv–vis spectrum show absorption edge at 440 nm which relates to pva-fe2o3 mixed with au which means there is a red shift after incorporation of au in the composites. and the energy gap of composite became equal to 2.48 ev after adding au solution.
