신규 합성 청색재료를 사용한 백색 유기발광소자의 광학적$\cdot$ 전기적 특성평가
Analysis of the Optical and Electrical Properties of a White OLEDs Using the newly Synthesized Blue Material
초록
백색발광은 풀칼라, 백라이트 및 조명을 위한 전자발광 소자로의 응용에 매우 중요하다. 본 논문에서는 오렌지 발광을 내는 Rubrene 색소를 포함하는 청색 재료인 nitro-DPVT 박막을 사용한 단분자 유기 백색발광소자를 구현하였다. 제작된 소자의 기본적 구조는
White light emission is very important for applying electroluminescent device to full display, backlight and illumination light source. In this letter, Multilayer molecular organic white-light-emitting device using thin nim of blue material nitro-DPVT with fluorescent dye Rubrene for an orange emission were fabricated. The basic structure of the fabricated device is a-NPD / nitro-DPVT / nitro- DPVT:Rubrene / BCP/ Alq3. Aluminum is used as the cathode material and ITO was anode material. The white light emission spectrum covers a wide range of the visible region and the Commission Internationale do I'E clairage (C.I.E.) coordinates of the emitted light was ((0.3347, 0.3515) at 14V. The turn voltage is as low as 2.5V and quantum efficiencies are
