本文研究了酞菁铜（CuPc）、N，N '-二-1-萘基-N，N'-二苯基-1，1 '-联苯-4，4'-二胺（α-NPD）和三（8-羟基喹啉）铝（Alq 3）有机电致发光器件在633 nm激发下的斯托克斯和反斯托克斯拉曼散射。由于共振拉曼效应，所有观察到的谱带都归因于酞菁铜。通过测量483 cm-1振动的反斯托克斯与斯托克斯拉曼散射的强度比，获得了CuPc层的温度。在400 mA下操作的器件中的CuPc层的温度为140 °C。
We have measured the Stokes and anti-Stokes Raman scattering from organic light-emitting diodes based on copper phthalocyanine (CuPc), N,N'-di-1-naphthalenyl-N,N'-diphenyl-1,1'-biphenyl-4,4'-diamine (α-NPD), and tris(8-quinolinolato) aluminum(III) (Alq3) with excitation at 633 nm. All of the observed bands have been attributed to CuPc because of the resonance Raman effect. The temperature of the CuPc layer has been obtained by taking the intensity ratio of anti-Stokes to Stokes Raman scattering of the 483 cm-1 vibration. The temperature of the CuPc layer in the device operated at 400 mA was 140 °C.
