Laser　direct　writing　(LDW)　is　a　promising　approach　for　fabricating　metallic　micropatterns　on　transparent　substrates　for　transparent　electronic　circuits　that　satisfy　both　electronic　and　optical　criteria.　However,　high　efficiency　and　precision　patterning　remain　a　challenge　for　both　photochemical　and　photothermal　LDW.　Here,　a　novel　method　is　proposed　with　a　femtosecond　laser　to　achieve　a　highly-efficient　photothermal　process　via　single-photon　absorption　by　photosensitive　particles　(SPA-FsLDW).　The　dispersive　photosensitive　particles　act　as　numerous　heating　sources,　enabling　simultaneous　multiple-location　photothermal　reactions　and　highly-efficient　metallization　due　to　heat-induced　metal　ion　reduction.　The　new　approach　effectively　exploits　the　excellent　heat-input　regulation　with　the　ultrashort　pulse　of　the　femtosecond　laser　to　achieve　great　temperature　controllability　and　precision.　It　is　shown　that,　with　a　deposition　rate　of　approximate　to　10(7)　mu　m(3)　s(-1)　and　electrical　resistivity　of　approximate　to　10(-7)　omega　m,　SPA-FsLDW　improves　efficiency　and　electrical　resistivity　by　at　least　one　order　of　magnitude　compared　to　previously　reported　FsLDW.　A　self-powered　sensor　is　fabricated　using　SPA-FsLDW,　demonstrating　its　practical　applicability.
