| description |
This thesis describes novel experimental methods in solution doping based on dipping (nonselective
area) and dripping via a syringe/pipette (selective area doping). Silica soot layers
deposited via Flame Hydrolysis Deposition were pre-sintered prior to solution doping. The
doped pre-sintered soot was then consolidated to form dense silica layers. The variations in the
number of pores, layer thickness, and dopant (erbium) concentration play major roles in the
quality of the resulting glass layer.
Optimisation and subsequent characterisation of the pre-sintered layers in terms of
surface morphology and structure were carried out. It was found that samples pre-sintered at
850C were optimal, allowing solution doping to be performed. Saturation of the dipping
period was achieved within 20 minutes following immersion of the sample into an erbium-trichloride
in de-ionised water solution.
In selective area doping, both single and multi-cycle dripping approaches were
adopted. Erbium ion concentration increased as the number of droplets increases. Ring
effects were also observed at high droplet counts. |
