The effect of solution temperature on chemically manufactured cds samples
(S.C. Virtual Company of Phisics S.R.L, 2021) Bal,I.; Baykul,M.C.; Saraç,U.
In this paper, CdS samples were chemically coated onto glasses from an aqueous cadmium acetate solution. The resultant samples were analyzed depending on the solution temperature (ST) varied between 65 and 85 °C. Structural analysis confirmed that the ST plays a significant role on the crystallinity. A better crystallization was achieved at the ST of 80 °C. The direct optical band gaps were found to be in the range of 2.18 to 2.42 eV. The ST exhibited a remarkable influence on the surface morphology. Increasing ST from 65 to 80 °C significantly reduced the surface roughness and particle size. The sample chemically produced at the ST of 85 °C exhibited the highest surface roughness and the largest particle size. There was a good relationship between the energy band gap and the surface morphology. Further morphological analysis showed that the ST does not play a role on the surface texture. The highest crystallinity, the lowest surface roughness, the smallest particle size, the lowest band tail energy and the highest optical band gap (2.42 eV) were obtained for the sample manufactured at the ST of 80 °C, indicating that the optimum ST was 80 °C under the applied experimental conditions. © 2021, S.C.
