Type: article
Abstract: In 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 HNaB 4 was employed. Different types of characterization such as X–ray diffraction (XRD), scanning electron microscopy (SEM), energy dispersive X–ray (EDX), transverse electron microscopy (TEM), atomic force microscopy (AFM), ultraviolet absorbance (UV) and Fourier transform infrared spectrometry (FT–IR) were occupied to the developed of Bi 2 Te 2.4 Se 0.6 nanocrystalline powders and pellets. According to the measurement results, Bi 2 Te 2.4 Se 0.6 thermoelectric material was obtained in nano dimensions.
