SITE-DEPENDENT STUDY OF THE OPTICAL PROPERTIES OF EU3+ IN PURE AND CHLORINE-DOPED FLUOROZIRCONATE GLASSES

摘要

For the present study, the emission spectra and lifetimes of EU(3+) in fluorozirconate and fluorochlorozirconate glasses were measured site dependently using the fluorescence line narrowing (FLN) technique. At high excitation energies, two different types of Eu3+ sites can be distinguished in fluorozirconate glass. The introduction of chloride into this glass caused a significant effect at low excitation energy. [References: 21]
