Abstract

The photoacoustic (PA) effect of cadmium sulfide (CdS) quantum dots on titanium dioxide (TiO2) prepared by successive ionic layer adsorption and reaction (SILAR) method was investigated. The CdS quantum dots were deposited over TiO2 nanoparticles and CdS: TiO2 films with different SILAR cycles (0, 2, 4, 6, 8 cycles). The results of maximum acoustic signals were 179.8, 196.8, 221.5, 235.4, and 253.9 µV, respectively. In addition, the corresponding energy band gap values were 3.34, 2.82, 2.55, 2.5, and 2.35 eV, respectively. The results of the PA measurement showed that the increased number of SILAR cycles improved the visible absorption, and the greatest absorbance at a wavelength of 490 nm is affected by the CdS bandgap energy. The lower the energy band gap, the more absorbance wavelength deviates towards a longer wavelength.
