It　is　urgent　to　develop　anti-high-energy　short-wave　blue　light　films　for　preventing　retinal　damage.　Carbon　quantum　dots　(CQDs)　with　robust　optical　tuning　properties　are　potential　candidates　for　addressing　the　issue.　Here,　bright　yellow　CQDs　(Y-CQDs)　with　quantum　yields　up　to　71%　are　synthesized　via　the　alkali-catalyzed　molecular　fusion　strategy,　which　demonstrates　excellent　anti-short-wave　blue　light　performance.　To　construct　anti-short-wave　blue　light　WLEDs,　the　flexible　transparent　Y-CQD/PVA　films　are　manufactured　by　mixing　Y-CQDs　and　PVA,　whose　short-wave　blue　light　conversion　performance　is　further　verified　by　being　applied　on　R-,　G-,　B-LEDs,　and　WLED.　Furthermore,　a　series　of　biological　experiments　regarding　retinal　protection　from　photochemical　damage　is　further　conducted,　verifying　that　the　Y-CQD/PVA　films　(&　GE;20　wt%)　have　a　significant　protective　effect　on　the　retina.　Our　discoveries　endow　CQDs　with　a　permit　into　the　field　of　light　conversion　and　will　propel　the　progress　of　carbon-based　optical　materials　for　manufacturing　forward-looking　anti-short-wave　blue　light　films　and　devices.
