Yb -Doped BaTiO

Several studies with Yb or Er active BaTiOs ceramics have been conducted due to their large number of optical applications such as frequency conversion, light modulation, optical switching, and optical memory storage. In particular, when a matrix is doped with trivalent Er , green and red infrared emissions at about 1.0 and 1.5 pm are obtained. 

Finally, different thermal treatments were carried out on the xerogels prepared by the different routes at 300, 500, 700, 950, and 1150 °C for 1 h. Also, undoped BaTiOs powders were prepared with chelating agents, using a similar procedure, as a reference.
