Digital Library of Periodicals of National Academy of Sciences of Ukraine| Резюме: | Organic light emitting devices have been so very much improved lately that they are being widely applied for
displays and lighting. Among many improving technologies, annealing processes in different atmospheres affect
greatly their performance, for instance when the active material is the small molecule Alq3. In particular, a significant
increase of the photoluminescence is observed in thin films of this molecule between 150 and 180 °C, before
the physical destruction of the films occurs at higher temperatures. This phenomenon is attributed to a phase transition
towards a novel morphological aggregation of the molecules in the film, which proved to be a much improved
optical material for luminescent applications, and which seems common to other molecules as well.
