RETRACTED: Properties of organic light-emitting diodes by aluminum cathodes modification using Ar+ ion beam

Reason:This article is retracted at the request of the editor as it is a duplication of a paper that has already appeared in at least nine other publications. As such this article represents a severe abuse of the scientific publishing system. It has wasted the time of many reviewers and also wastes costly journal space which is explicitly reserved for publishing original, not self-plagiarized work. Organic Electronics takes a very strong view on this matter. The editors want to inform our readership and authors, that those who publish multiple copies of their papers in Organic Electronics and elsewhere will lose their rights to further publication in this journal.
