Polycrystalline as-grown (AG) or chem-mechanically polished (CMP) undoped diamond\/BDD layers were investigated with respect to boron content and laser wavelength (800, 1030 nm). Boron incorporation leads to an increase in IR optical absorption and reduction of required energy fluence (?th \u2248 1 J cm\u22122 ) needed for sp3 to sp2 carbon conversion. Raman spectroscopy was performed to identify carbon conversion stages and to tailor the ideal parameters for other IR laser sources and required sp2\/sp3 carbon ratio. Electrochemical parameters (??p and ?Ap\/?Cp ratio) were obtained from cyclic voltammetry measurements of outer-([Ru(NH3 )6 ] 3+\/2+) and inner-([Fe(CN)6 ] 3\u2212\/4\u2212) sphere redox markers. Values of ??p and ?Ap\/?Cp are mainly influenced after conversion of 10% of sp3 to sp2 carbon. This trend is most pronounced for the [Fe(CN)6 ] 3\u2212\/4\u2212 redox marker, by decrease or increase of these parameters on AG or CMP BDD electrodes respectively. Electrochemical findings were supported by electrochemical impedance spectroscopy where ?ct keeps the same trend as ??p values and double layer capacitance profoundly increases between 10 and 25% of surface conversion.<\/p>\n<p><a href=\"https:\/\/www.sciencedirect.com\/science\/article\/pii\/S0169433223019487?via%3Dihub\">Read the full article.<\/a><\/p>\n","oddelovace":"none"}]},"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v23.9 -
