The　low-speed　spin-coating　method　was　developed　to　prepare　uniform　and　interconnected　silver　nanowires　(AgNWs)　film　with　the　transmittance　of　95%　and　sheet　resistance　of　20　Omega/sq　on　glass,　which　was　comparable　to　ITO.　The　fitting　value　of　sigma(dc)/sigma(op)　of　299.3　was　attributed　to　the　spin-coating　process.　Advantages　of　this　solution-processed　AgNW　film　on　AlGaInP　light-emitting　diodes　(LEDs)　as　transparent　conductive　layer　were　explored.　The　optical　output　power　enhanced　100%,　and　the　wavelength　redshift　decreased　from　12　to　3　nm,　which　indicated　the　AgNW　films　prepared　by　low-speed　spin-coating　possessed　attractive　features　for　large-scale　TCL　applications　in　optoelectronic　devices.
