Özet
The present study was conducted to obtain Cu:ZnO nanoparticles by precipitation technique from chemical bath deposition wastes and to characterize the samples by various techniques to determine their size, morphology, band gap and defect energy states. In this work, Zn1-xCuxO nanoparticles (x= 0.025, x=0.050, and x=0.075) were synthesized by co-precipitation technique using chemical bath deposition wastes of Cu:ZnO thin films. The XRD evaluation showed that the well-crystalline hexagonal wurtzite ZnO indexed peaks. Average crystallite sizes were found to be around 35.6-42.9 nm range by using the Debye-Scherrer equation. Surface mor- phology results showed that dense layer of nano-roses and less nanorods formations in low Cu-concentrated (x=0.025 and x=0.050) samples. The optical absorption edge shifted slightly to the higher wavelength from 350 nm to 375 nm with decreasing copper concentration, as mentioned the blue shift. Blue shift might be caused an increase in optical band gap from 3.14 eV to 3.28 eV due to the decrease in Cu concentration. In this study, the preferred co- precipitation technique was performed by using the wastes of chemical bath deposition. This work aims to produce high quality Cu:ZnO nanoparticles and investigate their optical properties by using “Chemical Bath Deposition” wastes of Cu:ZnO films. In this way, the recovery of chemical bath deposition waste and the production of thin films and nanoparticles from a single solution might be possible.
