Amorphous　YbF3:Er　light　conversion　film　has　been　successfully　fabricated　by　the　electron-beam　deposition　method.　The　amorphous　film　is　featured　with　a　transmittance　above　95%　in　the　region　of　300-2000　nm,　with　a　smooth　and　homogeneous　surface.　Moreover,　the　film　emits　strong　656　nm　red　light　upon　excitation　by　both　378　nm　and　980　nm　light.　Depending　on　the　highly　transparent　characteristics　and　promising　ultraviolet　and　near-infrared　conversion　properties,　the　developed　film　reveals　a　high　potential　in　application　of　novel　light　conversion　devices,　especially　in　solar　cells.　(C)　2013　Elsevier　B.V.　All　rights　reserved.
