We explored for the first time the ability of a three-dimensional polyacrylonitrile/ZnO material-prepared by a combination of electrospinning and atomic layer deposition (ALD) as a new material with a large surface area-to enhance the performance of optical sensors for volatile organic compound (VOC) detection. The photoluminescence (PL) peak intensity of these one-dimensional nanostructures has been enhanced by a factor of 2000 compared to a flat Si substrate. In addition, a phase transition of the ZnO ALD coating from amorphous to crystalline has been observed due to the properties of a polyacrylonitrile nanofiber template: surface strain, roughness, and an increased number of nucleation sites in comparison with a flat Si substrate. The greatly improved PL performance of these nanostructured surfaces could produce exciting materials for implantation in VOC optical sensor applications.

“…Surprisingly, the SnO 2 (2 0 0) peak intensity of the ML-Ni/FTO (0.9 J/cm 2 ) film was higher than that of the L-Ni/FTO (0.9 J/cm 2 ) film, suggesting that magnetic field had a positive effect on improving film crystallinity during laser annealing [33]. In addition, due to partial release of internal stress within the FTO layers of all the annealed Ni/FTO films, the position of the SnO 2 (2 0 0) peaks shifted toward higher 2Â angles as compared to the as-prepared Ni/FTO film [34].…”

“…2. This shift is owing to the gradual reduction of the residual stress in the Sn0.04Co0.06normalO2 layer 49 . Furthermore, the full width at half maximum (FWHM) of diffraction peaks of allow planes is affected by increasing the exposure time of the He-Ne laser, which indicates possible changes in the crystallite size and microstrain.…”

. The influence of He-Ne laser radiation on linear and nonlinear optical characteristics of Co-doped SnO2 (Sn0.04Co0.06O2) thin film was studied before and after irradiation. 22 mW (633 nm) He-Ne laser beam was employed to irradiate the film with different exposure times (Texpo. = 1, 2, 5, 15, 20, 40, and 60 min). As grown and irradiated films were examined by X-ray diffraction (XRD), an atomic force microscope (AFM) was integrated with UV-VIS–NIR spectrophotometer. XRD pattern analysis showed that the crystallite size decreased as the exposure increased to 5 min, however, a further increase in Texpo from 15 to 60 min increased the crystallite size. Analysis of AFM micrographs shows that the roughness of the surface and root mean square roughness of the film depend on the increase in the laser exposure time. The optical studies of irradiated films show that the optical energy gap Eg decreases as the exposure time increases to 5 min and then raises as the film is irradiated for up to 60 min. This reduction was attributed to the elimination of the additional oxygen from the film, and the increase of Eg is explained by the Burstein–Moss effect. Swanepoel’s envelope method is used to calculate the linear optical parameters of the irradiated film from the light transmission spectrum, such as refractive index n, and extinction coefficient k. The results reveal that the global behavior of n and k increases with exposure time. The oscillator parameters of the irradiated film of different exposure times were evaluated from the single-oscillator Wemple–DiDomenico model, which was then used to calculate the nonlinear optical parameters such as n2 the nonlinear refractive index, and χ(3) the third-order nonlinear optical susceptibility. It is concluded that the He-Ne laser irradiation with different exposure times enhances the optoelectronic properties of Sn0.04Co0.06O2 nanocrystalline semiconductor thin film
