We　demonstrate　a　novel　approach,　to　rapidly　fabricate,　conductive　silver　electrodes　on　transparent　flexible　substrates　with　high-bonding　strength　by　laser-ditect　writing.　A　new　type　of　silver　ink　composed　of　silver　nitrate,　sodium　citrate,　and　polyvinylpyrrolidone　(PVP)　was　prepared　in　this　work.　The　role　of,PVP　was　elucidated　for　improving　the　quality　of　silver　electrodes.　Silver　nanoparticles　and　sintered　microstructures　were　simultaneously　synthesized　and　patterned　on　a　substrate　using　a　focused　405　nm　continuous　wave　laser.　The-writing　was　completed　through　the　transparent　flexible　substrate,　with　a　programmed　2D　scanning,　sample　stage.　Silver　electrodes　fabricated　by　this　approach　exhibit　a　remarkable　bonding　strength,　which　can　withstand　an　adhesive　tape　test　at　least　50　times.　After　a　1500　time　bending　test,　the　resistance　only　increased　5.2%.　With　laser-induced　in-situ　synthesis,　sintering,　and　simultaneous　patterning　of　silver　nanoparticles,　this　technology　is　promising　for　the　facile　fabrication　of　conducting　electronic　devices　on　flexible　substrates.
