Abstract
A spectroscopic investigation of the host matrix KGd2F7 is performed using
Eu3+ as local probe. Its crystal structure derives from the fluorite-type b
y an ordering of the cations and anions. On powdered samples with different
europium concentrations, the luminescence spectra of Eu3+:KGd2F7 allowed a
n identification of a multisite behaviour for the Eu3+ ions, leading to a l
ifetime distribution for the D-5(0) emitting level.
