通过将微腔引入有机掺杂红光OLED器件 ,获得了半宽 (FWHM)仅为 2 7nm的纯红光发射 ,器件色度为 (0 .6 497,0 .3488) 另外通过改变基质材料 ,制作了不同的掺杂器件 ,发现除了器件的发光颜色有了很大变化外 ,器件的性能也有很大不同 ,采用宽能隙材料作为基质的器件无论在J V特性还是在器件效率上均不如窄能隙材料器件 ,说明在选基质材料时 ,除了一些必须考虑的因素外 ,材料的能隙也是决定器件性能的一个重要指标
By introducing the microcavity into an OLED device with organic doping, a pure FWHM emission of only 27 nm was obtained. The chromaticity of the device was (0.6987,0.3488). By changing the matrix material, Different doping devices were fabricated and found that the performance of the device is greatly different from that of the device. The devices with wide bandgap materials are not as good as JV or device efficiency Energy gap material devices, indicating that in the selection of matrix materials, in addition to some factors must be considered, the material’s energy gap is also an important indicator of device performance
