PZT: Eu 3+ sol-gel thin films and bulk samples were synthesized by sol-gel method. The crystalline structure (perovskite) was obtained in these materials by heat treatment at different temperatures. The temperature for the films was lower than that used in the bulk samples to obtain the perovskite-type phase. X-ray diffraction shows the presence of the perovskite phase in both kinds of materials. Emission and excitation studies of the impurity Eu 3+ were made to determine its luminescence
