Quantum　dots　(QDs)　have　attracted　broad　attention　owing　to　their　unique　advantages　in　micro-scale　light-emitting　diodes　(µLED).　However,　the　color　converted　µLEDs　prepared　by　pure　QDs　will　have　low　stability　and　luminous　efficiency.　The　combination　of　QDs　and　ordered　mesoporous　materials　(OMMs)　can　effectively　improve　the　luminescent　performance　of　µLED.　This　paper,　from　the　properties　via　simulation　and　experiment,　studies　the　influence　of　QDs/OMMs　composites　on　the　properties.　The　luminescence　properties　of　QDs/OMMs　composites　were　studied　by　instrument　characterization.　The　µLED　model　with　OMMs　was　established　based　on　finite　difference　time　domain　(FDTD)　method,　and　the　light　extraction　efficiency　(LEE)　of　µLED　in　the　three　central　wavelength　ranges　was　explored　respectively.　The　simulation　results　show　that　the　LEE　of　µLED　doped　with　SBA　reaches　89.5%,　which　is　40%　higher　than　that　doped　with　MCM.　More　importantly,　the　µLED　doped　with　OMMs　designed　in　this　paper　can　achieve　a　high　luminous　efficiency　of　79.2%　in　the　red　light　range　and　83.2%　in　the　green　light　range.　The　QDs/OMMs　composites　designed　are　applied　to　µLED,　and　the　high　LEE　is　realized　in　three　same　central　wavelength　ranges,　which　provides　a　new　direction　and　strategy　for　the　preparation　of　GaN-based　µLED　devices.　©　2023　SPIE.
