Paper Abstract

A quick and easy method for monitoring phase separation in glasses based on transmittance spectra is described. The spectra are recorded after different intervals during heat-treatment of doped or undoped glass samples and chromaticity x and y values are obtained therefrom. The results can be depicted graphically in x/y color charts for various temperatures and doping levels. The influence of the dopant ions on the phase separation becomes readily evident when doped and undoped samples of the same host glass composition are compared. The examples discussed are ternary sodium borosilicate glasses with Nd3+ and P5+ as dopants.
