Mawonekedwe osinthika okhala ndi ulusi wa LED

Ulusi wa LED, wopangidwa ndi Korea Institute of High Technology KAIST, akuwoneka kuti ali ndi kuthekera kongogwira ntchito ngati ulusi, zoluka zowala, kapena maziko opangira nsalu zomwe zimawonetsa zithunzi. Ma prototypes osinthika omwe amadziwika mpaka pano adatengera gawo lapansi lolimba. Yankho la Korea ndilosiyana kwambiri.

Kupanga ulusi wa LED, asayansi amaviika ulusi wina wotchedwa polyethylene terephthalate mu njira ya poly(3,4-dioxyethylenethiophene) yokhala ndi sulfonated polystyrene (PEDOT:PSS) ndikuumitsa pa 130°C. Kenako amalowetsanso muzinthu zotchedwa polyphenylene vinyl, polima yomwe imagwiritsidwa ntchito popanga zowonetsera za OLED. Pambuyo kuyanikanso, ulusiwo umakutidwa ndi osakaniza a lithiamu aluminium fluoride (LiF/Al).

Asayansi, pofotokoza njira yawo m'magazini apadera a Advanced Electronic Materials, akugogomezera kugwira ntchito kwake poyerekeza ndi njira zina zogwiritsira ntchito zipangizo za LED kuzinthu zazing'ono za cylindrical.
