Abstract	Undoped and Al-doped tin dioxide nanoparticles have been prepared by co-precipitation method in powdered and sintered pellet form. X-ray diffraction of samples have confirmed that all samples are of SnO$_{2}$ nanoparticles, polycrystalline in nature with crystallite size 50 nm and lesser. Field emission scanning electron microscopy and energy dispersive spectroscopy have been used to confirm the size and composition of nanoparticles, respectively. Electrical measurements of samples have been carried out in frequency range of 100–100 kHz at intervals of 20 °C in temperature range 40–160 °C. Ac conductivity of sample shows dependency on both frequency and temperature. For undoped samples ac conductivity is governed by multiple hopping processes at room temperature and by correlated barrier hopping model at higher temperatures. However, Al doped SnO$_{2}$ exhibits overlapping large polaron tunnelling model. From impedance analysis effect of grain boundary due to doping has been studied. It is also found that ac conductivity of samples increases with doping of Al.
