Abstract
Description
例えば、電子輸送層(ETL:Electron Transport Layer)が有機発光層(EML)と陰極の間に位置するようになると、陰極から発光層に注入された電子の大部分は正孔と再結合するために陽極の方へ移動する。
(1)先ず、透明な基板上に陽極物質を被覆する。陽極物質として主にITO(インジウム錫酸化物)が用いられる。
(2)その上に正孔注入層(HIL)を被覆する。正孔注入層として主に銅フタロシアニン(CuPC)を10nmないし30nmの厚さで被覆する。
(3)その後、前記正孔注入層上に正孔輸送層(HTL)を被覆する。このような正孔輸送層としては、4,4'−ビス[N−(1−ナフチル)−N−フェニルアミノ]ビフェニル(
4,4'−bis[N−(1−naphthyl)−N−phenylamino]−biphenyl(NPB)を30nmな
いし60nm程度蒸着して被覆する。
(4)その上に有機発光層を形成する。このとき、必要に応じてドーパントを添加する。
青色発光の場合、主に有機発光層として4,4'-N,N-ダイカルバゾールビフェニル(4,4'-N,N-dicarbazolebiphenyl(CBP)を厚さ30〜60nm程度蒸着し、ドーパントとしてはビス(2-(4,6−ダイフルオルフェニル)ピリジル−N,C2')イリジウム(III)ピコリネート(bis(2-(4,6-difluorophenyl)pyridyl-N,C2')iridium(
III)picolinate(Firpicと称する)が多用されている。
(5)その上に電子輸送層(ETL)及び電子注入層(EIL)を連続的に被覆するか、或
いは電子注入運送層を形成する
青色発光の場合、4−ビフェニルオキソラトアルミニウム(III)ビス(2-メチル-8-キノリナト)4-フェニルフェノレート) (4-biphenyloxolato aluminum(III)bis(2-methyl-8-quinolinato)4-phenylphenolate)(BAlq3と称する)が優れた電子注入/輸送線を有するため多用されている。
(6)続いて陰極を被覆し、最後に保護膜を重ねて被覆する。
ここで、有機発光層は下記の化学式1のホスト物質を含んで構成されている。
,3'、5,5'-tetracarbazolbiphenyl(TCBP))として、次のように合成される。
1.3,3'、5,5'-テトラブロモビフェニル(3,3'、5,5'-tetrabromobiphenyl)の合成
)(14.0mL、0.035mol)を徐々に滴下した後、10分間攪拌させる。
L)を別の容器に入れて攪拌させる。
基板を真空チャンバーに装着し、基本圧力が1×10-6torrとなるようにした後、有機物をITO上に正孔注入層(60nm)、NPD(20nm)、TCBP+Firpic(8%)(20nm)、BAlq3(10nm)、Alq3(30nm)、LiF(0.5nm)、Al(100nm)の順序で成膜した。
1mAで158cd/m2(8.09V)を表し、この際、CIE(Commision Internationale de L′Eclairage)はx=0.202、y=0.392であった。
前記NPD、Firpic、BAlq3、Alq3は下記の化学式2の通りである。
