Abstract：

White-light　emissive　hybrid　perovskites　have　received　continuous　attention　because　of　their　potential　applications　in　solid-state　lighting　and　displays.　However,　there　have　been　limited　reports　about　dual-emissive　white-light　hybrid　perovskites,　although　they　enable　a　wide　range　of　emission　switching.　Here,　we　report　a　one-dimensional　hybrid　perovskite,　(N-AEP)2Pb2Cl10·H2O　(NAPC,　N-AEP　=　1-piperazineethylammonium),　which　exhibits　dual-emissive　photoluminescence　with　a　wide　emission　switch　ranging　from　blue　to　orange.　Significantly,　tunable　white-light　emission　from　“cold”　white　light　(0.25,　0.29)　to　“warm”　white　light　(0.40,　0.42)　can　be　easily　observed　by　finely　tuning　the　excitation　wavelength.　Under　excitation　at　335　nm,　a　“cold”　white　light　with　chromaticity　coordinates　(0.31,　0.33)　close　to　those　of　“optimal”　white　light　(0.33,　0.33)　is　achieved.　Furthermore,NAPCexhibits　a　color　rendering　index　reaching　93.4,　which　is　among　the　highest　values　currently　reported　from　white-light　emissive　hybrid　perovskites.　This　work　paves　a　way　to　tune　the　photophysical　properties　of　hybrid　perovskites,　and　highlights　their　potential　for　solid-state　lighting　applications.　©　The　Royal　Society　of　Chemistry　2020.
