Abstract: Spectral and luminescent properties of Dy³⁺-doped quartz glasses produced by sintering nanoporous glass matrices are studied. The results of studies of the chemical composition and structure of the obtained samples with different content of Dy³⁺ ions are presented. The range of the optimal dysprosium concentration (0.05–0.08 at. %) is determined, at which concentration quenching of luminescence does not occur. A microstructured fibre with a nanoporous dysprosium-doped glass core is fabricated, and its luminescent properties are examined.

Keywords: nanoporous glass, optical fibre, dysprosium, luminescence.
