چکیده انگلیسی
Needle-like zinc oxide with high electrical conductivity has been successfully prepared in large-scale from calcining the need-like precursor synthesized by a simple co-precipitation approach with ZnCl2 as Zinc source, GaCl3 as Gallium source and NH4HCO3 as precipitant under an optimized conditions (45 °C and pH = 7.4–7.5). The as-fabricated products were characterized by means of TEM, SEM, XRD, EDS and XPS. Their electrical conductivities were also studied, showing that the volume resistivity of the needle-like zinc oxide with 2.2 mol% Ga3+ dopant was lower than 20 Ω·cm.
