Luminescent　materials　such　as　Cd-based　quantum　dots,　CuInS2　quantum　dots,　and　perovskite-based　materials　play　an　important　role　as　an　exceptional　class　of　optoelectronic　materials　due　to　their　unique　and　novel　characteristics　for　optoelectronic　applications.　However,　a　key　challenge　for　luminescent　materials　and　devices　is　their　poor　long-term　stability,　which　is　typically　attributed　to　the　irreversible　changes　of　surface　ligands　or　chemical　structure　against　oxygen　and　moisture　when　exposed　to　ambient　atmosphere.　Thus,　this　review　mainly　focuses　on　recent　important　work　on　the　stability-enhanced　strategies　of　luminescent　materials.　Various　strategies　for　their　fabrication,　including　surface　engineering　and　surface　coating　routes　have　been　summarized,　followed　by　their　advantages　and　challenges.　Furthermore,　the　corresponding　optoelectronic　applications　of　these　promising　stability-enhanced　luminescent　materials　in　light-emitting　diodes,　photodetectors,　solid-state　lighting　chips,　and　solar　cells　were　also　reviewed.　Afterward,　the　outlook　and　perspective　are　presented.
