Low temperature CBD growth of CdS on flexible substrates: Structural and optical characterization

摘要: Abstract This paper aims to optimize the synthesis of in-situ CBD CdS thin films deposited on flexible substrates. The deposition temperature is a sensitive parameter which strongly affects optical and structural properties needs be as low possible compatible with substrates technology. We show that it allow good quality plastic foil polymer (PE-LD) Experimental analyses based X-Ray diffraction confirm pure cubic structure (111) unique preferential orientation. However, crystallinity depends in range 45–95 °C has been found 65 °C optimal temperature. SEM micrographs homogeneous, compact smooth surface remarkable average grain sizes varying from 22 32 nm depending bath UV–Visible measurements, performed substrates, reveal highest transmittance (∼90%) at optimized 65 °C, band gap energy around 2.42 eV. These results demonstrate growth (polymer type), temperature, improves physical paves way integrate this process embedded application systems.
