In Situ Femtosecond-Laser-Induced Fluorophores on Surface of Polyvinyl Alcohol for H<sub>2</sub>O/Co<sup>2+</sup> Sensing and Data Security
In situ fluorophores were induced on polyvinyl alcohol (PVA) bulk materials by direct femtosecond laser writing. The generation of fluorophores was ascribed to localized laser-assisted carbonization. The carbonization of PVA polymers was confirmed through X-ray photoelectron spectroscopy analysis. T...
