Moreover, these studies show how a good TE material can be developed. TE materials hold the key to the essential ahead in energy alteration and storage, both of which are crucial in order to meet the protest of universal heating and the finite nature of fossil fuels. The characterization of nanostructure materials represents an enormous challenge as the structured and crystalline dimension are beyond the structural and optical view ( Ju and Kim 2016, Nomura et al. 2015, Park et al. 2016). AbstractIn this study, the selenium (Se) doped bismuth telluride (Bi 2 Te 3 ) nanocrystalline material synthesis by using a simple chemical route was presented. The bismuth (III) nitrate pentahydrate Bi(NO 3 ) 3 .5H 2 O, telluride dioxide TeO 2 and Se powder were dissolved by nitric acid HNO 3 . Herein, the two-step co-precipitation chemical route by using the sodium hydroxide NaOH and sodium borohydride NaBH 4 was employed. Different types of characterization such as X-ray diffraction (XRD), scanning electron microscopy (SEM), energy dispersive X-ray (EDX), transmission electron microscopy (TEM), atomic force microscopy (AFM), ultraviolet absorbance (UV) and Fourier transform infrared spectrometry (FT-IR) were occupied to the Bi 2 Te 2.4 Se 0.6 nanocrystalline powders and pellets which were developed. According to the measurement results, Bi 2 Te 2.4 Se 0.6 thermoelectric material was obtained in nano dimensions.
