Nonlinear photovoltaic behavior of these Sillenites are also reported here for the first time and explained by the presence of shallow along with deep photovoltaic centers.engAcesso RestritoPhotorefractive materialsNonlinear optical materialsPhotovoltaicNonlinear photovoltaic effect in Sillenite photorefractive crystalsArtigo10.1016/j.optmat.2017.01.028
