Computer modelling of hafnium doping in lithium niobate
Romel M. Araujo, Mario E. G. Valerio, Robert A. Jackson
Lithium niobate, LiNbO3, is an important technological material with good electro-optic, acousto-optic, elasto-optic, piezoelectric and nonlinear properties. Doping LiNbO3 with haf…

Mechanism of luminescent enhancement in Ba2GdNbO6:Eu3+ perovskite by Li+ co-doping
Marcos Vinicius dos Santos Rezende, Mario Ernesto Giroldo Valério, Rodolpho Mouta +2
We investigated the Li+ ion incorporation in Ba2GdNbO6:Eu3+ perovskite by atomistic simulations based on energy minimization. We predicted the most probable sites occupied by Eu3+…

Thermally Assisted Tunneling: An Alternative Model for the Thermoluminescence Process in Calcite
J. F. de Lima, M. E. G. Valerio, E. Okuno
In this work we investigate the effect of gamma and ultraviolet radiations on the thermoluminescence of Brazilian calcite. The irradiated samples presented three TL peaks at 150, 2…
