“…Up to now, various growth approaches have been used for the synthesis of Alq 3 nano-or microstructures [23][24][25][26][27][28][29][30][31]. Partially, different variants of vacuum evaporation of Alq 3 have resulted in the creation of ne nanowires and microcrystals with a clear hexagonal morphology [23,26,29].…”

Optical properties of composite structure based on ZnO microneedles and Alq3 thin film

The composite material based on ZnO microneedles and Alq 3 thin lm has been obtained. The photoluminescence study shows a tenfold enhancement in the band-edge UV emission (390 nm) of ZnO microneedles and 2x enhancement in visible emission of the hybrid composite, when excited by 266 nm laser beam. This enhancement can be explained by the interaction between ZnO and Alq3 molecules and the energy transfer from ZnO to Alq 3 molecule.

“…Crystallization is central to many commercial processes and is complex due its sensitivity to a wide range of solutions and ambient conditions (e.g., temperature, concentration, humidity, nucleation sites). − Much research effort has been directed at studying and controlling crystallization, including optics, − semiconductors, , pharmaceuticals, − and others. , Different techniques such as microfluidic or hanging drop methods are used to study crystal growth, − but, in most cases, a preferred direction of crystal growth is not controlled. , …”

Directed Growth of Orthorhombic Crystals in a Micropillar Array

et al. 2017

We report directed growth of orthorhombic crystals of potassium permanganate in spatial confinement of a micropillar array. The solution is introduced by spontaneous wicking to give a well-defined film (thickness 10-15 μm; volume ∼600 nL) and is connected to a reservoir (several microliters) that continuously "feeds" the evaporating film. When the film is supersaturated, crystals nucleate and preferentially grow in specific directions guided by one of several possible linear paths through the pillar lattice. Crystals that do not initially conform are stopped at an obstructing pillar, branch into another permitted direction, or spontaneously rotate to align with a path and continue to grow. Microspectroscopy is able to track the concentration of solute in a small region of interest (70 × 100 μm) near to growing crystals, revealing that the solute concentration initially increases linearly beyond the solubility limit. Crystal growth near the region of interest resulted in a sharp decrease in the local solute concentration (which rapidly returns the concentration to the solubility limit), consistent with estimated diffusion time scales (<1 s for a 50 μm length scale). The ability to simultaneously track solute concentration and control crystal orientation in nanoliter samples will provide new insight into microscale dynamics of microscale crystallization.
