Abstract

Crystal growth of Alq₃ was achieved in an ionic liquid by vacuum vapor deposition. Alq₃ crystals of several tens of microns in size showed beautiful hexagonal morphologies, different from previous reports. The successful crystal growth can be explained by the enhanced migration of Alq₃ molecules and moderate supersaturation within the ionic liquid. The Alq₃ crystal showed unique optical properties, such as a waveguide and blue-shift of the photoluminescence spectrum.
