Ultrasonical colloid chemistry deposition (UCCD) has been widely used to fabricate columnar-structured cadmium sulfide (CdS) thin films with ultra-fine particles. In conventional UCCD, the ultrasonic source is installed outside the reaction bath. In this study, an ultrasonic homogenizer was used as the ultrasonic source and was immersed directly in the bulk solution. The advantages of the ultrasonic homogenizer include homogeneous deposition, fine mixing, and enhancement of the ion-by-ion reaction. We compared the physical properties of CdS thin films prepared with and without ultrasound by using an X-ray diffraction, scanning electron microscope, atomic force microscope, and 3D surface analyzer and UV-Vis-NIR measurements.
