中文摘要：
使用新型红光磷光材料R-4B作为微腔有机电致发光显示器（OLED）的发光层，高反射A1阴极和半透半反Al阳极为微腔的两端反射镜。制备的’器件结构为A1（10nm）／MoOx（Ynm）／NPB（40nm）／TCTA（10nm）／CBP：R-4B（4％）（30nm）／BCP（10nm）／AlQ（40nm）／LiF（1nm）／Al（100nm）。讨论了腔长的变化对器件性能的影响。结果表明，微腔结构可以使光谱窄化，随着MoOx厚度y的增加，其峰值波长由600nm增至668nm。当MoOx厚度为40nm时，其发光强度最大，峰值波长为608nm，半高宽（FWHM）为50nm，器件的最大亮度为35300cd／cm2，最大效率可达23．5cd／A，得到了性能较好的红色磷光OLED。
英文摘要：
The microcavity organic light-emitting device （OLED） was fabricated with highly reflective Al cathode and the semitransparent Al anode. The device structure is as follows. AI（10 nm）/MoOx （Y nm）/NPB（40 nm）/TCTA（10 nm）/CBP.R-4B （4%）（30 nm）/BCP（10nm）/A1Q（40 nm）/LiF（1 nm）/ Al（100 nm）, where R-4B is employed as red phosphor emitting layer. The effect of cavity length on OLED property is discussed in this paper. It＇s indicated that the spectrum is narrowed and the color purity is increased. With the increase of MoOx thickness, the light-emitting peak changes from 600 nm to 668 nm. The optimal electroluminescent performance is observed in the sample with the MoOx thickness of 40 nm.the emitting peak wavelength is 608 nm,the full width at half maximum is 50 nm,the maximum brightness reaches 35 300 cd/cm2 ,and the maximum current efficiency is 23.5 cd/A. Red organic phos phor electroluminescent devices with stable luminescent properties are obtained.
