Confocal Scanning Raman Spectroscopy (CSRS) of an operating organic light-emitting diode, AIP Conference Proceedings, 1267, NA, 700-701, 2010.0094-243XAUT: HGO00803;http://hdl.handle.net/10400.1/3316Organic molecules with semiconducting properties are becoming nowadays core of the organic-based electronic era. Although organic light emitting diodes (OLEDs) have already matured for commercial applications, they still require longer device lifetimes. Some of the long-standing challenges in OLED technology relay on degradation and failure mechanisms. Several authors observed that degradation and subsequent damage of OLEDs is accompanied by formation of dark non-emissive spots [1-2]. Implementation of the confocal scanning Raman spectroscopy (CSRS) measurements helps to understand the chemistry, physics of OLEDs and moreover to have better confidence on their quality assurance.engRaman spectroscopyOrganic compoundsPolymersLight-emitting devicesConfocalOrganic semiconductorsLight emitting diodesconference object2014-01-0210.1063/1.3482761
