It is argued that some organic materials play an important role in preventing the formation of nonemissive species and enhancing the intrinsic stability of Alq3thin films. In the present work, films (Alq3pure, Alq3+ORGMAT (top), and Alq3doped with same) were grown on glass and silica substrates by thermal evaporation. Excitation, fluorescence, and transmission spectra have been measured, and the intensity of the green photoluminescence as a function of time has been monitored. Preliminary results show an improved stability of the emission in the doped Alq3films compared with the undoped ones. © 2002 Elsevier Science B.V. All rights reserved.
