Abstract
The luminescence of Bi3+-activated LaGaO3 is evaluated in the temperature range of 15.0 to 400 K. The Stokes shift of the Bi3+ emission is small (0.75 eV). Thermal quenching of Bi3+ luminescence in LaGaO3 is due to energy transfer between the Bi3+ ions, to host lattice quenching sites. It is concluded that the optical properties of Bi3+ are not influenced by the Ga3+ ions (3d10) of the LaGaO3 host lattice. A comparative study of the Bi3+ ion luminescence in the perovskites LaAlO3, LaGaO3, and LaInO3 is presented.
