Optimization of sintering temperature in CdZnS films using reflection spectroscopy

In the present investigation, the polycrystalline films of Cd X Zn 1– X S were prepared using a sintering technique. We coated slurry consisting of CdS, ZnS in the desired proportion—CdCl 2 (as adhesive) and ethylene glycol (as binder)—onto the glass substrates. The films were sintered at a range of...

Description
Summary:In the present investigation, the polycrystalline films of Cd X Zn 1– X S were prepared using a sintering technique. We coated slurry consisting of CdS, ZnS in the desired proportion—CdCl 2 (as adhesive) and ethylene glycol (as binder)—onto the glass substrates. The films were sintered at a range of temperatures in air atmosphere for the optimization of sintering temperatures using reflection spectroscopy. It was noticed that below 500°C, CdS-dominated films were obtained, and above 500°C, ZnS-dominated films were obtained. The films of desired composition giving appropriate results are obtained at 500°C. The reason is easily understood through reflection spectroscopic studies. Thus, we found 500°C to be the optimum sintering temperature and 10 min was the proper sintering time.
