Bu çalışmada, basit bir kimyasal yol kullanılarak gerçekleştirilen selenyum Se katkılı bizmut tellürür Bi2Te3 nanokristalin malzeme sentezi sunulmuştur. Bizmut III nitrat pentahidrat Bi NO3 3.5H20, tellürür dioksit TeO2 ve Se tozu nitrik asit HNO3 ile çözülmüştür. Burada, sodyum hidroksit NaOH ve sodyum borohidrid NaBH4 kullanılarak iki aşamalı birlikte çökeltme kimyasal yolu denenmiştir. Bunun sonucunda, geliştirilen Bi2Te2.4Se0.6 nanokristalin tozları ve peletlerinin ölçümleri için X-ışını kırınımı XRD , taramalı elektron mikroskopisi SEM , enerji dağılımlı X-ışını EDX , transvers elektron mikroskobu TEM , atomik kuvvet mikroskobu AFM , ultraviyole absorbansı UV ve Fourier dönüşümü kızılötesi spektrometresi FT-IR cihazları kullanılmıştır. Elde edilen ölçüm sonuçlarına göre nano boyutlarda Bi2Te2.4Se0.6 termoelektrik maddesi elde edilmiştir

In this study, the selenium Se doped bismuth telluride Bi2Te3 nanocrystalline material synthesis by using a simple chemical route was presented. The bismuth III nitrate pentahydrate Bi NO3 3.5H2O, telluride dioxide TeO2 and Se powder were dissolved by nitric acid HNO3. Herein, the two–step co–precipitation chemical route by using the sodium hydroxide NaOH and sodium borohydride HNaB4 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 Bi2Te2.4Se0.6 nanocrystalline powders and pellets. According to the measurement results, Bi2Te2.4Se0.6 thermoelectric material was obtained in nano dimensions.
