Optical and Structural characterization of pure and zinc-doped lead oxide nanostructures synthesized by chemical root method

Our goal in this research was to obtain pure and zinc doped lead oxide nanostructure through chemical root method. 0.04 M aqueous solution of lead nitrate and zinc chloride was mixed with 0.08 M aqueous solution of sodium hydroxide for making reaction solution. 0.001 M aqueous solution of TEA ((Tri Ethanol Amine) was also added to reaction solution. The prepared pure and Zn doped lead oxide nanostructure was characterized by Fourier transformation infrared spectroscopy(FTIR), X-ray diffraction (XRD), energy dispersive X-ray analysis (EDAX), scanning electron microscopy (SEM) and high resolution-transmission electron microscopy (HRTEM) and selected area electron diffraction pattern (SAED) pattern reveals the crystalline nature of the sample. The prepared pure and doped lead oxide consists of the average crystallites about 12 and 5 nm respectively. Optical band gap of pure and doped lead oxide sample are 5.17 and 5.5 eV obtained respectively. The photoluminescence (PL) spectra were investigated for both the sample. The PL spectrum shows peaks in UV region at 356 nm, blue regions around 421 nm and in green region around 544 nm. The spectra show a strong emission band around 421 nm.
