In　this　paper,　the　highly　ordered　periodic　silver　nanosphere　arrays　are　fabricated　by　vacuum　evaporation　based　on　anodic　aluminum　oxide　(AAO)　template.　The　diameter　and　spacing　of　silver　nanosphere　in　the　arrays　are　adjusted　just　by　controlling　the　thickness　of　evaporation.　Furthermore,　this　can　effectively　modulate　the　absorption　peaks　and　bandwidths　in　ultraviolet-visible-near-infrared　regions.　The　measurement　results　of　absorption　spectra　show　that　the　nano-arrays　have　obvious　electromagnetic　wave　absorption　characteristics　in　the　ultraviolet,　visible　and　near-infrared　bands.　The　finite-difference　time-domain　theoretical　simulation　combined　with　experiments　is　used　to　analyze　the　physical　mechanism　of　light　absorption　characteristics　in　different　wavebands.　The　ultraviolet　strong　absorption　is　due　to　the　Fano　resonance　induced　by　asymmetric　dielectric　environment　of　silver　and　aluminum;　the　visible　absorption　originates　from　local　surface　plasmon　resonance　of　silver　nanoparticles;　the　near-infrared　strong　absorption　is　attributed　to　the　surface　lattice　resonance　of　silver　nanosphere　arrays.
