The alloying effects on the structural and optical properties of nanocrystalline copper zinc oxide thin films fabricated by spin coating and annealing method

Copper zinc tin sulfide (CZTS) thin films were deposited by spin coating procedure of a sol-gel prepared from the solution of copper (II)chloride, zinc acetate, tin (II) chloride and thiourea in 2-methoxyehtanol followed by annealing under two different atmospheres viz. N2 gas and Sulphur (S) powder at 530 °C for 5 minutes. The effect of different annealing atmosphere on the structural and optical properties of the CZTS thin films were investigated. The X-ray diffraction study showed higher intensity peaks for films annealed under N2 gas ambient. SEM study revealed that the surfaces of the films in both cases are non-uniform. Films annealed in N2 gas atmosphere showed better absorption coefficient (exceeding 104 cm-1 in the visible region) than the sulphurized ones. The optical band gap (Eg) of the films were found to be in the range of 1.46 - 1.53 eV.Bangladesh J. Sci. Ind. Res.53(1), 13-20, 2018

Undoped and Co-doped zinc oxide (CZO) thin films have been prepared by spray pyrolysis technique using solution of zinc acetate and cobalt chloride. The effect of Co dopants on structural and optical properties has been investigated. The films were found to exhibit maximum transmittance (~90%) and low absorbance. The structural properties of the deposited films were examined by x-ray diffraction (XRD). These films, deposited on glass substrates at (400? C), have a polycrystalline texture with a wurtzite hexagonal structure, and the grain size was decreased with increasing Co concentration, and no change was observed in lattice constants while the optical band gap decreased from (3.18-3.02) eV for direct allowed transition. Other parameters such as Texture Coefficient (Tc), dislocation density (?) and number of crystals (M) were also calculated .
