Luminescence investigations of Ce3+-doped fluorozirconate and fluorohafnate glass phosphors
Abstrak
Ce3+ luminescence was studied in a flurozirconate glass in the ZrF4–BaF2–LaF3–AlF3–NaF (ZBLAN) and in a fluorohafnate HfF4-BaF2-LaF3-AlF3-NaF (HBLAN) glass systems under X-ray and UV excitation. Ce3+ luminescence temperature quenching in glasses in the temperature range 77–300 K was observed. The Ce3+ luminescence quenching in ZBLAN glass host is conditioned by two mechanisms: via the electrons ionization from the excited 5d-level of Ce3+ into the conduction band (CB); and quenching as a result of the intersection of the Ce3+ ground state and excited state potential curves. In HBLAN glass host the luminescence quenching is caused by the intersection of the Ce3+ ground state and excited state potential curves in the temperature range 77–300 K. The activation energies of Ce3+ luminescence quenching in ZBLAN and HBLAN have been determined.
