Input of nanoislands on the surface and nanoparticles in the bulk in SPR absorption. The optical density of SPR absorption peak due to nanoparticles in the bulk of the glass (triangle) and due to the nanoislands in MIF (inverted triangle). Hydrogen annealing temperature 120°C, ion exchange was performed at 325°C for 20 min. Inset: nanoparticles (NP) and nanoislands (NI) absorption peak in the absorption spectrum of 10-min annealed sample.
