Abstract

In this work we intend to obtain barium and strontium molibdates doped with Eu3+ and Tb3+ (BaMoO4:Eu3+, Tb3+ e SrMoO4:Eu3+, Tb3+. These materials will be characterized through the X-ray powder diffractrion (XRD), Scanning Electron Microscopy (SEM), Spectroscopy in the UV-Vis and IR range, besides the photolumienscent study using xenon lamp and argonium laser as excitation source . The lifetime of the Eu3+ and Tb3+ emissions samples will also be obtained. (AU)
