An in-situ measurement system for PDF and PL was developed to elucidate the correlation between the heat-treatment conditions and luminescence properties of crystallized glass phosphors. Evaluation of Eu-doped glass revealed that the ordering of the local structure during heat treatment contributes to the enhancement of luminescence properties. Additionally, while transparent crystallized glass was obtained at 800°C, transmittance was lost at 900°C due to the progression of crystallization. We will report the details of these crystallization behaviors and luminescence properties in the presentation.
