Single-layer films of organic compounds studied by spectroscopic ellipsometry

In this work, single layer 3,3′-Di(9H-carbazol-9-yl)-1,1′-biphenyl (mCBP), tris(4-carbazoyl-9-ylphenyl)amine (TCTA) and 4,6-Bis(3,5-di-3-pyridinylphenyl)-2-methylpyrimidine (B3PymPm) organic thin films optical properties were investigated by spectroscopic ellipsometry and spectrophotometer. Films were fabricated by thermal evaporation on glass, quartz, and indium tin oxide (ITO) substrates. The substrate impact on complex refractive index and absorption coefficient of thin films is evaluated and discussed.
