Kafukufuku Pazida Zatsopano Ndi Perovskite Kukonzekera Ma LED Ogwira Ntchito Kwambiri a US

frontp wochokera ku United States Florida State University kafukufuku gulu linapanga mtundu watsopano wa kuwala-emitting diode (LED), pogwiritsa ntchito organic - wosakanizidwa wosakanizidwa zinthu zimene zingatulutse zotchipa, nyali zowala ndi zowonetsera. Wothandizira Pulofesa backpfrontp wakuthupi Hanwei Gao (kumasulira: High Han Wei) ndi pulofesa wothandizana naye wa uinjiniya wamankhwala BiwuMa (kumasulira: Mabi Wu) akugwiritsa ntchito gulu la zida zodziwika kuti perovskites organometallic halide kupanga nyali zamasitediyamu za LED zowoneka bwino kwambiri. Adzaphunzira zofalitsidwa m'magazini ya 'advand materials'. ntchito ya backpfrontp yapitayi idapeza kuti perovskite ikhoza kukhala chinthu chodalirika popanga kuwala kwamphamvu kwa LED, mkulu wa Han Wei adati. Komabe, machitidwe ake sanakwaniritsidwe mokwanira. Tikukhulupirira kuti pali mwayi wowongolera. backpfrontp M'mbuyomu, ofufuza ena anayesa ndi perovskite kupanga LED bwalo floodlights, koma sangathe makamaka kothandiza. High Han Wei ndi Mabi Wu amakhulupirira kuti ngati kuli koyenera kusintha njira, organic - inorganic osakaniza kuti apange nyali zapamwamba za LED kuti zigwire bwino ntchito. backpfrontp Tikaganizira za mtundu uwu wa zinthu, timadziwa kuti ziyenera kukhala ndi ntchito yabwino, adatero Mabi Wu. Tikupangira njira yatsopano yothanirana ndi zovuta zina kuti tipange nyali yamphamvu kwambiri ya 1000W LED. Pambuyo pa miyezi ingapo pambuyo pa backpfrontp ndi kupanga mankhwala katundu wa zipangizo ndi zipangizo kulamulira kuyesera ntchito bwino ikukonzekera chipangizo dongosolo, iwo potsirizira pake kupitirira kuyembekezera mkulu ntchito LED. Zinthu zake ndi zowala kwambiri. backpfrontp adayezedwa pamagetsi oyendetsa a 12V, mphamvu yowala ya 10,000 candela pa lalikulu mita. Nthawi zambiri, pakompyuta, kuwala kowala kwa candela 400 pa sikweya mita nyali zochitira masewera olimbitsa thupi za LED zinali zowala mokwanira. backpfrontp kuwala kodabwitsaku kumadalira kwambiri chithandizo chapamwamba chotere, ma crystalline nanomaterials omwe ali ndi kuwala kowala kwambiri, adatero Han Wei. Kupanga backpfrontp nkhaniyi mofulumira komanso mosavuta. Mu labotale, mkulu wa Mabi Wu Han Wei ndipo pafupifupi ola limodzi kuti apange kuchokera kuzinthu izi, pafupifupi theka la nthawi adzatha kupanga chipangizo chathunthu ndi kuyesa. backpfrontp Komanso, ngakhale anabala wosanganiza perovskites wosakhazikika mu mpweya lonyowa, koma perovskite nanostructures chifukwa cha umagwirira pamwamba umapangidwira mwapadera, koma ali bata wabwino. Kukhazikika kwamankhwala koteroko kumachepetsa kupanga mtundu watsopanowu wa zofunikira za malo a LED mtsogolomo kuti zitheke kupanga phindu lalikulu. Kafukufukuyu wapita patsogolo kwambiri paukadaulo wowunikira magetsi a eyapoti ya LED, omwe ayamba kuchepetsa njira zogwiritsira ntchito mphamvu. Ngakhale pali zinthu zosiyanasiyana zowunikira za LED zomwe zimagulitsidwa pamsika, koma chifukwa cha mtengo wazinthu ndi zovuta zokhudzana nazo zidapangitsa kutchuka kwa kuyatsa kwamasewera a LED pang'onopang'ono. backpfrontp Komabe, nyali za LED zimapulumutsa mphamvu ndi mfundo yosatsutsika. Malinga ndi US Department of Energy, Kuwala kwa LED kwanyumba kuposa nthawi zonse kupulumutsa mphamvu ya incandescent osachepera 75%. backpfrontp ngati mutha kupanga magetsi otsika mtengo, owoneka bwino kwambiri a bwalo la tennis la LED, aliyense apita kukasankha, adatero Mabi Wu. Kwa makampani, njira yathu ili ndi mwayi waukulu, chifukwa mungathe njira yachuma kwambiri yolemeretsa zinthu zapadziko lapansi zitha kukonzedwa kuti mupange nkhaniyi. backpfrontp ogwira nawo ntchito akuphatikizanso kuyang'ana kwambiri paukadaulo wothandizira pulofesa waukadaulo waukadaulo wa LED Zhibin Yu (kumasulira: ku Zhibin), komanso pulofesa wothandizira wa chemistry Kenneth Hanson (Kenneth \u0026 middot; Hansen), anali wolemba nawo pepala. . backpfrontp mkulu Han Wei ndi Mabi Wu ndi Kenneth \u0026 middot; Hansen ndi mphamvu ndi zipangizo mu ndondomeko yolembera anthu olemba ntchito atsopano 11, kafukufuku Wothandizira Wachiwiri kwa Purezidenti W.Ross Ellington adatero. Ntchito yamakono, komanso zofalitsa zina zaposachedwa zikuwonetsa kudzera mu mgwirizano womwe ukuyembekezeka kukwaniritsidwa. kumbuyo
