We report on excitation of the photoluminescence of rare earth doped fluoride by means of the surface plasmon resonance of Al layer. The advantage of this method is high efficiency of the excitation, which is applicable to ultra-thin films. The p-polarized UV diode laser light is coupled to surface plasmon resonance using a fused silica prism in a Kretschman configuration. The angular dependence of reflected intensity is measured using a theta-2theta goniometer. The surface plasmon at resonance condition induces the luminescence in the adjacent doped fluoride layer. The luminescence is collected using a fiber optics and detected by a spectrophotometer. For the experiment, we used pure LiF films and doped by Eu, Pr and Yb. The fluoride layer was deposited on Al-coated fused silica substrate by electron beam evaporation. For the experiment, we prepared several samples with thickness up-to 20 nm.
