We have fabricated Organic Light Emitting Diodes (OLEDs) on nano-structured indium tin oxide films. The enhancement in extraction efficiency by a factor of 30% was found comparable to other expansive techniques for the fabrication of indium tin oxide layer. The electroluminescence spectra at viewing angles from normal to the substrates up to 600 off normal remain almost unchanged and does not show the angle dependence observed for other extraction efficiency enhancement techniques. The emission spectrum was also found to be stable with time for these OLEDs. The spectral uniformity with angle and time with enhanced extraction efficiency and cheap deposition technique could be of great interest for the application of down converted OLED.

Keywords: Organic Light Emitting Diodes (OLEDs), Electroluminescence (EL) spectra.
