A fluorescence study of self-assembled silica layers on D-shaped optical fibre
Fourth Asia Pacific Optical Sensors Conference, 2013•spiedigitallibrary.org
D-shaped optical fibres are coated with silica nanoparticles by horizontal dip and slide
method. Visual determination of film coverage is difficult. Thick coatings are discernible
through thin film interference coloring but thinner coatings require SEM imaging. Here, we
show that fluorescence imaging, using Rhodmaine B in this example, can provide some
qualitative assessment of coverage.
