In this paper, the synthesis of CdO nanoplatelets by the isothermal evaporation method in the presence of egg white (albumen) as a bio-template agent is reported for the first time. The morphological and microstructural characteristics of products obtained after drying at 130 °C and annealing at 300 °C have been investigated by Fourier transform infrared (FT-IR) spectroscopy, Thermogravimetric analysis (TGA), X-ray diffraction (XRD), SEM (Scanning Electron Microscopy), Transmission Electron Microscopy (TEM), Energy Dispersive Spectroscopy (EDS), and compared with corresponding samples obtained in the absence of template. The characterization techniques evidenced remarkable differences between the two sample typologies. Specifically, crystalline CdO in the cubic phase was obtained only in the presence of albumen. The samples were further analyzed by electrical conductivity measurement, ultraviolet spectral studies (UV) and photoluminescence (PL) to ascertain their possible use for optical and electrical applications.

Abstract
In this paper, the synthesis of CdO nanoplatelets by the isothermal evaporation method in the presence of egg white (albumen) as a bio-template agent is reported for the first time. The morphological and microstructural characteristics of products obtained after drying at 130 °C and annealing at 300 °C have been investigated by Fourier transform infrared (FT-IR) spectroscopy, Thermogravimetric analysis (TGA), X-ray diffraction (XRD), SEM (Scanning Electron Microscopy), Transmission Electron Microscopy (TEM), Energy Dispersive Spectroscopy (EDS), and compared with corresponding samples obtained in the absence of template. The characterization techniques evidenced remarkable differences between the two sample typologies. Specifically, crystalline CdO in the cubic phase was obtained only in the presence of albumen. The samples were further analyzed by electrical conductivity measurement, ultraviolet spectral studies (UV) and photoluminescence (PL) to ascertain their possible use for optical and electrical applications.Pubblicazioni consigliate
