Synthesis of Nickel-Doped Zinc Selenide Nanoparticles and Study of Structural and Optical Properties

Zinc selenide doped with nickel (Zn1-xNixSe) nanoparticles were synthesized using co-precipitation method with different compositions such as x = 0.1, 0.15, 0.2. Poly-vinyl-pyrrolidone was acted as a surfactant. The nature of as prepared samples was found crystalline and it was confirmed by using X-ray-diffraction (XRD) pattern. Along with it, the average crystallite size (D), dislocation density (δ) and micro-strain (ε) were calculated using XRD pattern. Ultra-violet visible (UV–visible) spectroscopy was employed for the calculation of optical energy band gap of the prepared nanoparticles. Nickel-doped zinc selenide nanoparticles are suitable choice for fabrication of nanoelectronic devices and also useful in optical storage devices.
