Hypothesis
How does annealing temperature affect the optical properties of CdS thin films deposited at low solution concentrations?
Conclusion
The study found that the optical properties of CdS films vary significantly with annealing temperature and solution concentration.
Supporting Evidence
- The films showed good adhesion and varied in thickness based on the annealing temperature.
- XRD analyses indicated a mixture of cubic and hexagonal phases in the films.
- Optical transmission ranged from 75% to 97% at different wavelengths.
Takeaway
This study looks at how heating CdS films changes their ability to let light through, depending on how strong the solution was when they were made.
Methodology
CdS thin films were deposited using the chemical bath deposition technique at two different concentrations and then annealed at various temperatures.
Limitations
The study does not explore the long-term stability of the films or their performance in practical applications.
