Izibonisi eziguqukayo ezinemicu ye-LED

Amafilamente e-LED, okusungulwe yi-Korean Institute of High Technology KAIST, abonakala enamandla okumane asebenze njengama-fibrous, amaluki akhanyayo, noma isisekelo sokudala izindwangu ezibonisa izithombe. I-prototypes yezibonisi eziguquguqukayo ezaziwayo kuze kube manje zazisekelwe ku-substrate eqinile ngokuqhathaniswa. Isinqumo samaKorea sihluke kakhulu.

Ukuze benze imicu ye-LED, ososayensi bacwilisa i-fibrous material ebizwa ngokuthi i-polyethylene terephthalate engxubeni ye-poly(3,4-dioxyethylenethiophene) ene-sulfonated polystyrene (PEDOT:PSS) bese bayomisa ku-130°C. Bese beyicwilisa bayibuyisele entweni ebizwa nge-polyphenylene vinyl, i-polymer esetshenziswa ekwakhiweni kwezibonisi ze-OLED. Ngemuva kokumisa kabusha, imicu igcotshwa ngengxube ye-lithium aluminium fluoride (LiF/Al).

Ososayensi, bechaza amasu abo kujenali ekhethekile i-Advanced Electronic Materials, bagcizelela ukusebenza kahle kwayo uma kuqhathaniswa nezinye izindlela zokusebenzisa izinto ze-LED ezakhiweni ezincane zamacylindrical.
