Application of Iterative Deconvolution Technique to Ion-Exchange Study of Glass

Potassium profiles measured with an electron microprobe along a normal to the surface of chemically strengthened sodium borosilicate glass were deconvoluted to correct for the finite resolution (∼3 μm) of the microprobe. The deconvolution procedure was conducted using a modified iterative Fourier te...

Description
Summary:Potassium profiles measured with an electron microprobe along a normal to the surface of chemically strengthened sodium borosilicate glass were deconvoluted to correct for the finite resolution (∼3 μm) of the microprobe. The deconvolution procedure was conducted using a modified iterative Fourier technique and an experimentally measured “beam function.” The latter measurement constituted the most important source of error, particularly since the beam function is influenced by density variations near the interface of the glass specimen and its mount. Marked improvements over results obtained using a constant beam function resulted when an empirical variable beam function was included in the deconvolution procedure.
