## Description

- description: |
    Fluorescence lifetime of Er3+ was measured for F-doped tellurite
    glasses with parallel heat treatment under a temperature gradient
    atmosphere in order to find the annealing condition to make transparent
    glass ceramics in which Er3+ ions are located in the precipitated
    crystals.  The preparation and annealing of the samples were performed
    in a vertical temperature gradient furnace, where molten glass was
    sucked into a pre-heated Pyrex glass tube.  The annealing temperature
    range is between 350 degC and 800 degC.  After the annealing
    treatment, time-resolved fluorescence emission of Er3+ (1.55um;
    excitation light source is 977nm) were measured sequentially along the
    tube.  The lifetime of the emission was about 2.6 msec for as-prepared
    glass.  We have found that the lifetime increased to 5.2 msec when the
    glass was annealed at 470 degC for 5 min and 550 degC for 5 min
    successively, although its transparency was lost.  This increase implies
    that the Er3+ ions are embedded in fluorine-rich phase to bring about
    reduced non-radiative emission.  We are now continuing to find the
    condition to get transparent glass ceramics.
