Item Study of Optical and Electrical Properties of Carbon Nanotubes (CNTS) Thin Film Deposited by Spray Pyrolysis Method for Optoelectronics Application(Dutse Journal of Pure and Applied Sciences, 2025-09) Oluwasusi, T V; Gurku, U M; Alayande, S O; Babalola, V A; Fasiku, Taiwo Bukola; Eneye, J; Sarki, M U; Idris, M M; Mundi, A A; Aribisala, A; Adeleye, M OCarbon nanotubes (CNTs) are novel material with exceptional optoelectronics properties. CNTs thin films have been used in many different applications. Despite its vast potential, particularly as a promising alternative to indium tin oxide (ITO) and silicon in transparent conducting films, research on CNT thin film remains surprisingly limited. This study creates CNT thin films at 0.1 M and 0.2 M concentration using the spray pyrolysis technique. This technique was used due to its low cost and its ease of use. The optical and electrical characteristics of CNTs thin films created on the sodalime glass substrates at 350 oC were studied in relation to precursor concentration. Ultraviolent Spectrophotometer (UV) and Four-Point Probe Technique characterized the thin films. With rising precursor concentration, CNTs thin films' optical band gap energy decrease. With rise in precursor concentration, the films' transmittance and electrical conductivity grow. The result of the study concludes that concentration has effect on the optical and electrical properties of CNTs thin films and that the high electrical conductivity, high transmittance, low absorbance and low optical band gap energy of the films makes it useful in optoelectronics devices.
