	1	Size effects on electrical properties of sol–gel grown chromium doped zinc oxide nanoparticles显示文摘In this communication, we report the results of the studies on electrical properties of Zn_(0.95)Cr_(0.05)O nanoparticles synthesized using sol–gel method. X–ray diffraction(XRD) and transmission electron microscopy(TEM) measurements were performed for the structural and microstructural behaviors of the nanoparticles. Rietveld analysis was carried out to confirm the single phasic nature. High resolution TEM(HRTEM) confirms the nanoscale nature and polycrystalline orientations in the samples. Dielectric response has been understood in the context of universal dielectric response(UDR) model along with the Koop's theory and Maxwell – Wagner(M–W) mechanism. Variation in ac conductivity with frequency has been discussed in detail in terms of power law fits. Results of the impedance measurements have been explained on the basis of crystal cores and crystal boundary density. Cole – cole behavior has been studied for the impedance data. For potential application of nanoparticles, average normalized change(ANC) in impedance has been estimated and discussed in the light of size effects and oxygen vacancies.
