Research Abstract

In this study, we investigated the relationship between the luminescence efficiency, local structures around rare-earth ions, and the glass structures of matrix glasses for the realization of high-luminescence-efficiency near-infrared glass phosphors. By extended X-ray absorption fine structure measurements, it was revealed that the first neighbor atom was Oxygen. In the case of the second neighbor atom was Boron, luminescence efficiency decreased. By high-energy X-ray diffraction measurements, it was revealed that the glass phosphor which has medium-range structures in the matrix showed higher luminescence efficiency.
