Uyini ukubonisa okuhlosiwe?

-Mapho na- Ingabe isifinyezo sokukhanya kwe-organic ekhipha i-diode, okusho ukuthi "ukukhanya okukhanyayo okukhipha ubuchwepheshe" ngesiShayina.Umqondo ukuthi i-organic. ukukhanya.Isakhiwo esiyisisekelo se-Mapho na- ukwenza ungqimba wezinto ezibonakalayo ezikhanyisa ama-nanometers obukhulu ku-Indium tin oxide (ITO) njengengqimba elimhlwitha elikhanyayo.above i-littit-emfit-emfingt-ukumisa ungqimba we-electrodes ngomsebenzi ophansi womsebenzi, wakhe isakhiwo njenge-sandwich.

ubuchwepheshe obuphezulu obuphakanyisiwe

I-substrate (ipulasitiki esobala, ingilazi, i-foil) - i-substrate isetshenziselwa ukusekela i-oled yonke.

I-Anode (esobala) - I-anode iqeda ama-elektroni (inyusa izimbobo "ze-elektroni" njengokugeleza kwamanje ngedivayisi.

Isendlalelo sokuhamba umgodi - Le ungqimba yenziwa ngama-molecule wezinto ezibonakalayo ezingenisa izimbobo "zezimbobo" ezivela ku-anode.

Isendlalelo se-luminescent - le ungqimba yenziwa ngama-molecule wezinto ezibonakalayo (ngokungafani nezendlalelo eziqhutshwa) lapho inqubo ye-luminescence yenzeka khona.

Isendlalelo se-Electron Transport - Le ungqimba yenziwa ngama-molecule wezinto ezibonakalayo ezingenisa ama-elektrode avela e-cathode.

Cathode (okungaba sobala noma i-opaque, kuya ngohlobo lwe-oled) - lapho kugeleza khona kwamanje ngedivayisi, ama-cathrode ajova ngogesi esifundeni.

Inqubo yeLuminescence ye-OLD imvamisa inezigaba ezinhlanu ezilandelayo:

Umjovo Wenkampani Yesithwali

I-Carriers Transport: Ama-elektroni ajobelwe kanye nezimbobo zithutha zisuka engxenyeni yezokuhamba ye-elektroni bese umgodi wokuhambisa ungqimba ku-luminescent ungqimba, ngokulandelana.

I-Carrier Prerier Recongnation: Ngemuva kokuthi ama-elektroni kanye nezimbobo zifakwe engxenyeni ye-luminescent, ziboshelwe ndawonye ukuze kwakhiwe ama-elektroni umgodi wababili, okungukuthi, ama-visitons, ngenxa yesenzo samandla e-coulomm.

④ Ukufuduka kwe-Exciton: Ngenxa yokungalingani kwe-elektroni ne-hole ezokuthutha, isifunda esikhulu se-Exciton ngokuvamile asimbozise lonke ungqimba lwe-luminescence, ngakho-ke ukufuduka okuguqukayo kuzokwenzeka ngenxa yeziqu zokuhlushwa.

I-⑤Exciton Radiation Degenerates Photons: Inguquko ekhazimulayo ye-Exciton ekhipha ama-Photon futhi akhiphe amandla.
