Effects of temperature on the optical and electrical properties of ZnO nanoparticles synthesized by solgel method
ZnO nanoparticles for different thermal treatment temperatures has been synthesized by solgel method. The structural, compositional and morphological properties of the powder were reported. The size of as-prepared nanoparticles is about 3554nm. The nanoparticles after thermal treatment at 500C in air shows a strong luminescence band around 384nm in the UV range. The imaginary and real parts of the sample impedance versus frequency, were studied in the range of 40Hz2MHz.
