Abstract
The spectral and luminescent properties of quartz glasses, obtained by sintering nanoporous glass matrices and activated with Dy3+ ions, have been investigated. The results of studying the chemical composition and structure of samples with different Dy3+ contents are presented. The range of optimal dysprosium concentration (0.05–0.08 at %) at which luminescence concentration quenching does not occur is determined. A microstructured fiber with a core made of nanoporous dysprosium-doped glass is fabricated, and its luminescent properties are investigated.
