description In the previous decade nanostructure materials have emerged as the necessary ingredient in electronic application and enhancement of device performance. Cobalt sulfide is one such transition metal sulfide which has provoked a lot of interest in the field of research. The present study was related to pure, (Al and Zn) doped cobalt sulfide NPs have been fabricated using facile co-precipitation method. The cubic structure has conformed to XRD analysis and crystallite size of pure and doped Co9S8 NPs in the range of 11 to 29 nm and with W-H method varies from 29 to 51 nm. The SEM micrograph shows that the agglomeration of the particles in the form of clusters. To conform the vibrational modes of (Al and Zn) doped Co9S8-NPs was done with Raman spectroscopy analysis. The absorbance of prepared materials was investigated with UV–VIS and it was also observed that the band gap decreased from 3.6 to 1.94 eV with doping agents. In case of IV analysis shows that the resistivity decreased and conductivity increased of Al and Zn doped Co9S8 NPs. Furthermore, the sharp increase in potential difference at lower temperature indicates that the doped material is an excellent thermoelectric material for energy storage devices.
