The 9/65/35 PLZT is a highly optical transparent material throughout the visible spectrum and its films are good candidates for wave-guides. On the other hand, Er3+- doped wave-guides are fabricated for integrated optic amplifiers, but the increase of Er concentration has a cut-off due to the strengthening of the ion-ion interaction. In this work, (Ag0/Au0, Er3+) - doped (Pb0.91La0.09)(Zr0.65Ti0.35)O3 films to produce planar wave-guides have been prepared by CSD processing on silica glass. The aim is to reinforce the fluorescence intensity by a resonant phenomenon between Er3+ and Ag0 or Au0 nanoparticles, and the dielectric effect of the matrix. This material is compared with other (Metal, Er3+) doped films.3+- doped wave-guides are fabricated for integrated optic amplifiers, but the increase of Er concentration has a cut-off due to the strengthening of the ion-ion interaction.
