“…Therefore, more extensive studies on the nanoforms of CdS semiconductor and their various properties have been carried out. A variety of chemical routes to synthesize CdS nanoforms have been employed [6,9,[14][15][16][17][18][19][20][21][22]. However, the co-precipitation technique is an important bottomup approach for the synthesis of nanoparticles.…”

This work presents a study on the surface morphology, structure and optical behavior of stable phase cadmium sulphide (CdS) nanoparticles synthesized via co-precipitation technique. Scanning electron microscopy (SEM) analysis has been employed to study a cluster formation in the aggregated nanoparticles. An image analysis approach using ImageJ has been used to measure the size of nanoparticles from the SEM micrographs. Fourier transform infrared spectroscopic (FT-IR) analysis identified absorption peaks of Cd-S stretching along with moisture content. X-ray diffraction (XRD) analysis showed that CdS nanoparticles crystallized in wurtzite structure with a preferential orientation along (0 0 2) plane. The particle size, microstrain and lattice constants have been evaluated using XRD data. The lattice parameters of these nanoparticles were found to be shorter than the bulk value which led to lattice contraction. The optical absorption study showed a blue shift in the fundamental absorption edge indicating a quantum size effect.

“…Throughout the deposition process S/Cd decreased gradually. The grain size of the film was calculated from the line broadening in the XRD pattern by using Scherer's formula [5,6] and is shown Table 1. The 5 min KMnO 4 substrate activated CdS thin film is amorphous in nature as shown in Figure 1.…”

“…Figure 2(a) shows the optical absorption for substrate activation time, and the maximum peak was observed at 15 min. A Tauc plot ( ℎ]) 2 as function of photon energy (ℎ]) for CdS thin films with various substrate activation time is shown in Figure 3 [6,7], and the optical energy gaps are shown in Table 1. There is a change in CdS band gap due to a change in different KMnO 4 activation time conditions [8].…”

The growth and properties of cadmium sulfide (CdS) thin films were prepared in a controlled manner using chemical bath deposition (CBD) method for different KMnO 4 activation time such as 5 min, 10 min, 15 min, 20 min, 25 min, and 30 min on glass substrates. CdS thin films are deposited on KMnO 4 activated glass substrates at 85 ∘ C with pH value of 10 for 30 min deposition time. In the chemical bath deposition (CBD) technique, KMnO 4 activation time plays an important role in the growth of the CdS film. The structure of the CdS film changes with respect to the rate of deposition. The size of the particles is affected by the nucleation rate if the solution does not contain the constant number of Cd 2+ and S 2− ions throughout the deposition process. This change in structure of CdS is confirmed by the XRD, SEM, and AFM analysis, and the ion-by-ion nucleation growth is also examined. The optical property of the prepared CdS thin film is scrutinized using UV-Vis-NIR absorption analysis.
