Abstract
We present one-pot colloidal synthesis of copper indium telluride (CITe) from respective metal salts with sodium tellurite in 1-octadecene with variation in surfactant and the reaction temperature between 200 and 300 °C. Oleic acid and/or oleyl amine are employed to initially, generate tellurides of individual element at intermediate stage. The tuning of reaction parameter including temperature variations play important role for the formation of phase-pure CuInTe2 nanocrystals with a band-gap of about 1.15 eV. The phase-purity was confirmed by XRD. EMI Shielding efficiency of CITe/PVA film can be enhanced to the tune of −8.84 dB by use of silver nano-particles. The composite can be suitable for X-band applications.
