Abstract
pre-treatment by dip coating in two detonation nanodiamond (DND) seeding media has been studied. The DND suspension in ethyl alcohol and dispersion of DND in dimethyl sulfoxide (DMSO) with polyvinyl alcohol (PVA) were chosen for the seeding purpose. The grain size distribution of nanodiamond particles in both seeding media was kept at the same level (approximately 1050 nm). After the seeding nanocrystalline diamond lms were deposited on the bres using microwave plasma assisted chemical vapour deposition system. The results of the process were investigated using numerical analysis of scanning electron microscopy images. The molecular structure of diamond has been examined with micro-Raman spectroscopy. Thickness, roughness and optical properties of the nanocrystalline diamond lms in VIS-NIR wavelength range were investigated on reference samples using spectroscopic ellipsometry. Light reection at the bre end-face for dierent deposition parameters was also investigated. Proposed seeding method can be further eectively applied for manufacturing of optical bre sensors. Due to extraordinary properties of diamond, which include high chemical and mechanical resistance, such lms are highly desired for optical sensing purposes.
