  "abstract": "An efficient and cost effective approach in the synthesis process of the bismuth telluride (Bi2Te3) powders and pellets were developed based on a chemical solution route. The route consists of dissolving of both the bismuth (III) nitrate pentahydrate, Bi(NO3)(3)center dot 5H(2)O and tellurium dioxide, TeO2 into the same inorganic nitric acid, HNO3 with the two-step precipitation of sodium hydroxide, NaOH and sodium borohydride, NaBH4. The different characterization parameters such as X-Ray Difflaction (XRD), Scanning Electron Microscopy (SEM, Energy Dispersive X-ray (EDX), Transmission Electron Microscopy (TEM, Atomic Force Microscopy (AFM), Ultra Violet (UT. absorbance and Fourier Transform InfraRed (FT-IR) spectrometry were carried out. As a result of these, the developed powders possessed a rhombo-hedral crystal structure exhibiting a nanocrystalline form with crystalline size about 10 nm. The elemental of Bi and Te were developed with their stoichiometric atomic ratio of (30.15): (48.19). Furthermore, the TEA/I micrographs showed an aggregate phenomenon and the primary crystalline size being quite low. Additionally, the produced Bi2Te3 pellets indicated a smooth surface with an average roughness value of 58 nm according to the AFM image. Absorption has occurred at about a range within 1 (arbitrary unit). Ultimately, the FTIR demonstrated that the C-H, O-H, C-O and C-S bonds were similar to the Bi2Te3 nanostructure materials.",
