Abstract:
A method for desorbing an adsorbate bound or bonded to a substrate wherein the adsorbate/substrate system includes at least two energy levels, the method comprising the steps of(a) selecting an electromagnetic wavelength that is approximately resonant with a transition between a first energy level and a second energy level; and (b) irradiating the adsorbate/substrate system with electromagnetic radiation at the selected wavelength thereby cleaving a bond in the adsorbate/substrate system, wherein the substrate is glass, and wherein the cleaved bond is selected from the group consisting of a silicon-oxygen substrate bond, a silicon-carbon adsorbate bond, a silicon-heteroatom adsorbate bond and a silicon-oxygen adsorbate/substrate bond.
