CTAB capped copper sulphide nanorods of size 6-8nm width and 40-60nm length has been synthesized by a simple aqueous co-precipitation method at room temperature. Powder X-ray diffraction pattern suggests the product obtained is pure hexagonal phased CuS(Covellite). The material exhibits very low optical transmittance in the UV region but more than 50% in the Visible and NIR regions. The photoluminescent reflectance decreases from UV region to visible region and increases drastically above 500nm. The AC electrical parameters, viz. dielectric constant, dielectric loss factor and AC electrical conductivity increase with the increase in temperature. Also, a higher dielectric constant and a lower AC electrical conductivity were observed. Results obtained indicate that quantum sized CuS nanorods with useful optical and electrical properties can be prepared by the simple method adopted in the present study
