“…A CS 2 out-of-phase stretching vibration was observed at 950 cm −1 and the band at 405 cm −1 corresponding to Cd-S stretching vibration mode. 20 In Figure 2(b), the O-H stretching at 3434 cm −1 was observed and the peak is very broad when compared to the as-synthesized complex, which is purely due to the adsorbed moisture by the sample. The peak observed at 2921 cm −1 evidenced the capping of the alkyl group over the formed CdS.…”

Cadmium sulphide (CdS) nanorods were prepared by a single precursor thermal decomposition (SPTD) method. The formation of CdS nanorods and their structure, morphology and elemental composition were studied by means of FT-IR, XRD, FE-SEM, HR-TEM and EDAX analysis. Photoluminescence (PL) and lifetime measurements were recorded to study the luminescence properties of the material. The PL spectrum of the CdS nanorods showed one broad peak and four shoulders and the cause for this emission was discussed. The PL emissions from the band edge and deep trap state of the CdS nanorods were studied by lifetime measurements. Further, the synthesized CdS nanorods showed an increase in efficiency of photocatalytic degradation of methylene blue (MB) and rhodamine B (RhB). The increase in the photocatalytic activity was attributed to the mixed phase of the CdS nanorods.

“…Numerous techniques have been used to grow CdS and Cd 1-x Zn x S thin films including dip coating [16], electrodeposition [17], chemical vapor deposition (CVD) [18], aerosol-assisted CVD (AA-CVD) [19][20][21], chemical bath deposition (CBD) [2,8,22,23], spray pyrolysis [24,25], thermal evaporation [26], successive ionic layer and reaction (SILAR) [27], thermolysis [28,29], electrochemical atomic layer epitaxy (ECALE) [11], sol-gel spin coating, [30,31] doctor's blade, [32] and others [14,21,33,34]. Spin coating (SC) is a particularly useful method for the deposition of thin films [35,36].…”

Thin films of Cd 1-x Zn x S (CZS) were prepared by a novel spin coating/melt method from cadmium ethylxanthato [Cd(C 2 H 5 OCS 2 ) 2 ] and zinc ethylxanthato [Zn(C 2 H 5 OCS 2 ) 2 ] in x ratios of 0-0.15 and of 1. A solution of the precursor(s) in THF was spin coated onto a glass substrate and then heated at 250°C for 1 h under N 2 . The thickness of the film formed can be controlled by varying the solution composition and/or the spin rate of the coating. A total metal precursor solution concentration of 50 mM was used in all cases. The films were characterized by p-XRD, SEM, EDX, ICP-AES, XPS, UV-Vis absorption spectroscopy, Raman spectroscopy and resistivity measurements. The band gaps of the films were between 2.35-2.58 and 3.75 eV (0 B x B 0.15 and at x = 1). The resistivity of Cd 1-x Zn x S films was found to vary linearly with zinc contents, and the properties of the films suggest potential application to photovoltaics as window layers. This work is the first study to demonstrate Cd 1-x Zn x S thin films by a spin coating/melt method from xanthato precursors.
