Nonwetting and optical properties of bn nanosheet films

Journal Article


Abstract


  • This study begins with a brief discussion on the high-temperature chemical vapor deposition synthesis of transparent boron nitride nanosheet films on silicon/silicon dioxide substrates. The compact nanosheets grew perpendicular to the substrate surface, and the majority of them had thicknesses of less than 5 nm. Ultraviolet-visible spectroscopy measurements demonstrated a wide optical band gap of ~5���6 eV of nanosheets, and cathode-luminescence spectroscopy showed their strong luminescence emission in the ultraviolet region. The nanor-ough surface morphology of the films induced nonwetting and self-cleaning features with water-contact angles reaching ~153��. Such transparent superhydrophobic films can be utilized for the preparation of nonwetting ultraviolet light-emitting surfaces for optoelectronics applications, antifouling surfaces on marine vessels or oil-water separation equipments.
