Green light devices with a top multilayer anode/EHI608/NPB/Alq3:ELL/ETL02/LiF/Mg:Ag/ out-capping layer configuration were experimentally prepared on silicon substrate.T he doping concentrations of emitting layer have strict effects on the driving voltages, luminances, efficiencies and electroluminescent(EL) spectra of OLED devices. Further, the microcavity characteristics of top-emitting green OLED devices were examined. Based on the transfer matrix theory and optical constants of materials, the transmission of multilayer thin films (ETL/EIL/Mg︰Ag/CPL) are numerically calculated with matlab program. The experimental results demonstrated that based on an increase in the dopant concentration of the guest materials, the electroluminescent (EL) efficiency, driving voltage and luminance of the organic light-emitting device increased. And the doped concentration of the guest is controlled at 3.5%, the efficiency of the device remained stable, the transmission of multilayer thin films (ETL/EIL/Mg︰Ag/ CPL) gradually increased, according to the increase in the CPL thickness of the cathode refractive index matching layers. When the CPL thickness is controlled at approximately 30 nm, the transmission in the entire visible range is maximized, and the transmission spectrum (CIEx, CIEy) value of multilayer thin films (ETL/EIL/Mg︰Ag/ CPL) are extremely near to the white equal energy (0.33, 0.33).项目、云南省技术创新人才培养项目（2017HB111）、云南省“万人计划”产业技术领军人才培养项目等资助。
