일반적으로 유기 발광 현상이란 유기 물질을 이용하여 전기에너지를 빛에너지로 전환시켜주는 현상을 말한다. 유기 발광 현상을 이용하는 유기 발광 소자는 통상 양극과 음극 및 이 사이에 유기물층을 포함하는 구조를 가진다. 여기서 유기물층은 유기 발광 소자의 효율과 안정성을 높이기 위하여 각기 다른 물질로 구성된 다층의 구조로 이루어진 경우가 많으며, 예컨대 정공주입층, 정공수송층, 발광층, 전자수송층, 전자주입층 등으로 이루어 질 수 있다. 이러한 유기 발광 소자의 구조에서 두 전극 사이에 전압을 걸어주게 되면 양극에서는 정공이, 음극에서는 전자가 유기물층에 주입되게 되고, 주입된 정공과 전자가 만났을 때 엑시톤(exciton)이 형성되며, 이 엑시톤이 다시 바닥상태로 떨어질 때 빛이 나게 된다. In general, organic light emitting phenomenon refers to a phenomenon of converting electrical energy into light energy using an organic material. An organic light emitting device using an organic light emitting phenomenon usually has a structure including an anode, a cathode, and an organic material layer therebetween. The organic material layer is often made of a multi-layered structure composed of different materials to increase the efficiency and stability of the organic light emitting device, for example, it may be made of a hole injection layer, a hole transport layer, a light emitting layer, an electron transport layer, an electron injection layer. When the voltage is applied between the two electrodes in the structure of the organic light emitting device, holes are injected into the organic material layer at the anode and electrons are injected into the organic material layer, and excitons are formed when the injected holes and the electrons meet each other. When it falls back to the ground, it glows.

ITO(인듐 주석 산화물)가 1,000 Å의 두께로 박막 코팅된 유리 기판을 분산제를 녹인 증류수에 넣고 초음파로 세척하였다. 이 때, 세제로는 피셔사(Fischer Co.) 제품을 사용하였으며, 증류수로는 밀리포어사(Millipore Co.) 제품의 필터(Filter)로 2차로 걸러진 증류수를 사용하였다. ITO를 30분간 세척한 후, 증류수로 2회 반복하여 초음파 세척을 10분간 진행하였다. 증류수 세척이 끝난 후, 이소프로필알콜, 아세톤, 메탄올의 용제로 초음파 세척을 하고 건조시킨 후, 플라즈마 세정기로 수송시켰다. 또한, 산소 플라즈마를 이용하여 상기 기판을 5분간 세정한 후 진공 증착기로 기판을 수송시켰다.A glass substrate coated with a thin film of ITO (indium tin oxide) at a thickness of 1,000 kPa was put in distilled water in which a dispersant was dissolved, and ultrasonically washed. At this time, Fischer Co. product was used as a detergent, and distilled water filtered secondly as a filter of Millipore Co. product was used as distilled water. After the ITO was washed for 30 minutes, the ultrasonic cleaning was repeated twice with distilled water for 10 minutes. After the distilled water was washed, ultrasonic washing with a solvent of isopropyl alcohol, acetone and methanol was carried out and dried, and then transported to a plasma cleaner. In addition, the substrate was cleaned for 5 minutes using an oxygen plasma, and then the substrate was transferred to a vacuum evaporator.
기판을 진공 챔버에 장착한 후 베이스 압력이 1 X 10-6 torr가 되도록 한 후 유기물을 상기 ITO위에 정공 주입 및 수송층으로 하기 DNTPD (700 Å), 정공수송 및 전자차단층으로 하기 NPB (300Å), 일반적으로 적색 인광 호스트 물질로 많이 사용되고 있는 하기 CBP를 호스트로서(95 wt%) 사용하고, 도판트로서 상기 Dp-6 (5 wt%)를 공증착(300 Å)하며, 전자수송층으로 Alq3 (350 Å), 음극으로 LiF (5 Å), Al (1,000 Å)의 순서로 성막하였다. 상기의 과정에서 유기물의 증착속도는 1 Å/sec를 유지하였고, LiF는 0.2 Å/sec, 알루미늄은 3~7 Å/sec의 증착속도를 유지하였다. After mounting the substrate in the vacuum chamber, the base pressure was 1 X 10 -6 torr, and the organic material was formed as a hole injection and transport layer on the ITO, followed by DNTPD (700 kPa), hole transport and electron blocking layer, NPB (300 kPa). The following CBP, which is generally used as a red phosphorescent host material, is used as a host (95 wt%), and the Dp-6 (5 wt%) is co-deposited (300 Å) as a dopant, and Alq 3 is used as an electron transport layer. (350 kPa) and a cathode were formed in the order of LiF (5 kPa) and Al (1,000 kPa). In the above process, the deposition rate of the organic material was maintained at 1 Å / sec, LiF was 0.2 Å / sec, and the aluminum was maintained at a deposition rate of 3 to 7 Å / sec.
