Zusammenfassung:	The disclosure relates to a method of forming an optical device including the steps of (i) providing a substrate carrying a first electrode capable of injecting or accepting charge carriers of a first type; (ii) depositing a polyfluorene over the first electrode; and (iii) forming over the polyfluorene a second electrode capable of injecting or accepting charge carriers of a second type, wherein the polyfluorene is heated before and after forming the second electrode. The disclosure has particular application in the preparation of organic light emitting devices.
