Portuguese Abstract: ABO3 amorphous materials, such as BaTiO3 (BT), SrTiO3 (ST), PbTiO3 (PT), and BaxSr1−xTiO3 (BST) have recently attracted a good deal of attention due to their ferroelectric and electro-optical properties. Intense photoluminescence at room temperature was observed in amorphous titanate doped with chromium (BaxSr1−xTi1−yCryO3) prepared by the polymeric precursor method. Results indicated that substantial luminescence at room temperature was achieved with the addition of small Cr contents to amorphous BaxSr1−xTi1−yCryO3. Further addition of Cr or crystallization were deleterious to the intensity of the luminescent peak obtained for excitation using λ=488.0 nm
