N2 - This contribution exhibits the luminescence properties of BaHfO3: Tb3+ perovskite ceramics. The main objective is to know the effect on the luminescent properties of the trivalent Terbium ion (Tb3+), when it is introduced into a crystalline structure of high symmetry such as perovskite, where it can occupy any of two sites available in the lattice. The synthesis of these nanocrystal powders was conducted by hydrothermal route. X-ray diffraction pattern showed crystallized cubic perovskite type structure with space group Pm-3m. Luminescence spectra showed emission peaks which are associated to the 5D4→7FJ (J = 2, 3, 4, 5, 6) typical transitions of trivalent terbium ion. Photoluminescence features were obtained as a function of Tb3+ doping concentration, being the sample doped with Tb3+ (5 at.%) the one presented the highest intensity peak emission. Also, some characteristics of the decay time, surface morphology, crystallite size and chemical composition of the studied powders, are shown.
