Mechanofluorochromic　materials　are　a　type　of　＇smart＇　material　because　of　their　adjustable　fluorescent　properties　under　external　mechanical　force,　making　them　significant　members　of　the　materials　family.　However,　as　the　fluorescent　characteristics　of　these　materials　highly　depend　on　their　microstructures,　the　still　insufficiently　in-depth　research　linking　molecular　structures　to　light　emission　motivates　researchers　to　explore　the　fluorescent　properties　of　these　materials　under　external　stimuli.　In　this　work,　based　on　synthetic　[AgS4]　microplates,　we　explore　a　fascinating　mechanical-induced　photoluminescent　enhancement　phenomenon.　By　applying　mechanical　force　to　solid-state　[AgS4]　to　damage　the　surface　morphology,　a　significant　enhancement　in　photoluminescence　is　observed.　Moreover,　the　emitted　intensity　increases　with　the　extent　of　damage,　which　can　be　attributed　to　alterations　in　crystallinity.　This　work　provides　valuable　insights　into　the　relationship　among　photoluminescence,　crystallinity,　and　mechanical　force,　offering　new　strategies　for　designing　luminescent　devices.　©　2024　American　Chemical　Society.
