Highly　stretchable　and　mechanically　foldable　electronic　devices　such　as　photodetectors　(PDs)　have　garnered　significant　attention　in　recent　years.　Nevertheless,　existing　devices　in　this　category　often　compromise　their　photosensitivity　and/or　response　time　in　order　to　achieve　the　desired　stretchability.　Here　we　present　a　novel　free-standing　stretchable　photodetector　constructed　using　electrospun　ferroelectric　P(VDF-TrFE)　nanofibers　(NFs)　adorned　with　boron　nitride　quantum　dots　(BNQDs).　The　incorporation　of　BNQDs　leads　to　a　remarkable　160.0　%　increase　in　the　Young＇s　modulus　of　the　composite　NFs　and　enhances　their　strain　capacity　to　an　impressive　120　%.　Furthermore,　it　significantly　augments　the　photoresponsivity　by　847.8　%,　primarily　attributable　to　the　abundant　trap　states　present　in　the　BNQDs.　Additionally,　we　discovered　a　strong　dependency　of　the　giant　photocurrent　(Iph)　on　the　channel　length　(l),　whereby　Iph　≈　1/l2.　Notably,　our　fabricated　devices　exhibit　exceptional　stretchability,　allowing　for　up　to　100　%　strain　while　maintaining　a　rapid　rise　time　of　approximately　15.6　ms　and　an　expeditious　decay　time　of　12.6　ms.　Our　findings　underscore　the　significant　potential　of　ferroelectric　polymer　NFs　decorated　with　BNQDs　in　the　realm　of　flexible　optoelectronic　applications.　©　2023
