In this study, we present the comparison of device performance measurements for organic light emitting diodes using a spectroradiometer through the viewing angle and integrating sphere, widely used for device measurements. The mean calculation method using these results was applied to convert the spectroradiometer (under different viewing angles) data to match with the integrating sphere measurements. The conversion of the spectroradiometer based quantum efficiency and electroluminescence data from all different angular emission patterns was similar to that of the integrating sphere data within a reasonable range of deviation. As such, it is possible to reduce the recurring costs and required time between these two measurement techniques by bypassing the integrating sphere measurement.

使用分光辐射计和积分球测量比较有机发光二极管的性能

在这项研究中，我们将通过分光辐射计通过视角和积分球对有机发光二极管的器件性能测量进行比较，该光谱被广泛用于器件测量。使用这些结果的平均值计算方法将分光辐射计（在不同视角下）的数据转换为与积分球测量值相匹配。在合理的偏差范围内，基于光谱辐射仪的量子效率和电致发光数据从所有不同角度发射模式的转换都类似于积分球数据的转换。这样，可以通过绕过积分球测量来减少这两种测量技术之间的重复成本和所需时间。
