Title: A study for optical and structural properties of CuInS2 nanoparticles

Abstract:

Copper indium sulfide (CuInS₂) is one of the most promising ternary materials to be used in many applications because of its suitable optical band gap, cost-effective and non-toxic. CuInS₂ nanoparticles have been synthesized at different copper to indium (Cu/In) molar ratios; 0.1, 0.5, 0.8, 1.2, and 1.4. Subsequently, these were deposited on glass substrates and under annealing temperature 300 ^°C via the electrospinning method. The optical properties have been analyzed at room temperature using UV-visible (UV-vis) spectroscopy which revealed a decrease in the optical bandgap from 1.52 to 1.32 eV with increasing Cu/In molar ratio. The structural properties have been analyzed in detail by X-ray diffraction (XRD), the patterns shown improvement in the quality and size of the ternary crystals with increasing the Cu/In molar ratio.
