Аннотация
The near-infrared (NIR) luminescence spectra and changes caused in them by an exposure to ArF excimer laser radiation were studied in bismuth-doped silica-based glasses containing Al, P or Ge and B additives. Experiments were conducted using specimens in the form of optical waveguides synthesized by surface plasma chemical vapor deposition (SPCVD), using bismuth-doped glass sample as the light-guiding core. Excited by ~808, ~904, and ~970 nm wavelength laser diodes, the NIR luminescence spectra were recorded in the 700–2000 nm wavelength range at temperatures of 105 and 300 K. The UV laser treatment was found to cause changes in both integrated intensity and spectrum shape of NIR luminescence associated with bismuth impurities. The observed changes are discussed with the assumption of photo-induced reconfiguring of different bismuth inclusions, which might present in the glass network in the form of separate ions and atoms, interstitial molecules, and bulk semiconductor nanoclusters.
