Annealing Effects

ABSTRACTOptical and infrared reflection spectra for Bi implanted silica are reported as a function of dose and thermal annealing. A series of high purity silica samples were implanted with Bi ions at an energy of 350 KeV. Doses were 1 × 1016 and 1.0 × 1017ions/cm2 at 5μamps/cm2. The samples were subsequently thermally annealed at 400, 600 and 800 C. The optical absorption from 6.2 to 1.8 eV and infrared reflectance from 5000 to 450 cm”−1 were measured before and after annealing. Effects of thermal annealing are strongly dependent on Bi content.

<p>Glass with compositions  xLiF–(30−x)Li<sub>2</sub>O –10WO<sub>3</sub>–60B<sub>2</sub>O<sub>3</sub>  for 5 ≤ x ≤ 25 mol% have been prepared using the normal melt quenching technique. The optical absorption and reflection spectra were recorded at room temperature in the wavelength range 300-800 nm. From the absorption edge studies, the values of the optical band gap (E<sub>opt</sub>) and Urbach energy (ΔE) have been evaluated. The values of E<sub>opt</sub> and ΔE vary non-linearly with composition parameter, showing the mixed alkali effect.</p>
