Effect of Thickness in Electroluminescence spectra on ( 2-5 dialoxy-PPV ) films


The optical properties and electroluminescence of ROPPV (2-5 – dialoxy-PPV) films of various thickness have been studied. The thickness of ROPPV layer on glass slide was measured by Fizeau fringes interferometric technique which varied from 200 to 400nm. The absorption spectra show that the absorption occurred only in ultraviolet region. Thick films show… (More)
