Abstract

The luminescent properties of lead-fluorosilicate nanostructured glass-ceramics doped with ytterbium and
erbium ions have been investigated. Luminescence spectra in visible and near infrared range at room (300 K) and low (77 K) temperatures have been measured at 975 nm wave length pumping. The glass-ceramics
luminescence spectra dependences on the secondary heat treatment time and sample temperature have been obtained.

Keywords: luminescent properties, rare-earth ions, low temperatures
