Features of J-aggregates formation in pores of nanostructured anodic aluminum oxide

Abstract

Features of J-aggregates formation in highly structured pores of anodic aluminum oxide (AAO) have been studied using steady-state absorption and luminescence spectroscopy and time-resolved luminescence spectroscopy. J-aggregates with different structures (spherical and thread-like) were chosen for the studying. Spectroscopic investigations show the presence of both types of the J-aggregates in the AAO pores. It leads to a static disorder increasing in the J-aggregates. Besides, in the case of the thread-like J-aggregates changes in the structure have been supposed also.
