Abstract By synthesizing gadolinium-doped LiAl5O8 sample via combustion method, electron paramagnetic resonance (EPR) and photoluminescence (PL) properties of gadolinium in the LiAl5O8 host were studied. From PL data, it was confirmed that gadolinium stabilized in the host system as Gd3+. The emission spectrum of the LiAl5O8 ceramic exhibited a sharp, narrow band associated with the transitions from the 6P7/2 excited state to the 8S7/2 ground state of Gd3+. EPR study revealed the presence of Gd3+ ions at distorted octahedral sites in the LiAl5O8 lattice.
