Optical Waveguide Formation in Quartz by Ion Implantationy isolates the surface crystal from the bulk. During implantation there are changes in the luminescence of the quartz which parallel the amorphisation..The present study has measured the efficiency of the process as a function of ion energy. Some initial measurements of annealing will be reported.

Physics of Ion Implantation (Ion Cascade Processes and Physical State of the Implanted Solid)rstanding of these processes and the resulting microstructural modifications is invaluable in utilizing ion implantation to “engineer”surfaces through the controlled modification of surface properties. This lecture summarizes current theoretical and experimental understanding in these areas. Basic i

The results showed complete substitutionality for the hafnium implantation.This position was not affected by annealing at 300°C. For lead and thallium it was found that only a fraction of the implanted ions oc

Optical Waveguide Formation in Quartz by Ion Implantationn of crystalline quartz reduces the refractive index by some 5%. To preserve the crystalline properties and fabricate planar optical waveguides we have used the technique of energetic light ion implantation of the quartz. This generates an amorphous layer at the end of the ion range which effectivel
