Mutlugun Research Group
MutlugunLab is devoted to the development of innovative nanocrystals for optoelectronic applications.
Our research effort is based on the synthesis of nanocrystals, i.e CdSe, InP, ternary alloy based quantum dots, perovskites; the demonstration of stand-alone nanocrystalline polymer films; the study of photophysical properties of composite structures; the development of high-stable materials of 2-dimensional colloidal nanosheets; utilization of nanocrystals for colloidal optoelectronic applications: passive (photoluminescence-based), active (electroluminescent-based) nanocrystalline materials of light emitting diodes, lasers and solar cells.
At the same time, our research feeds the studies of NANOME to generate high added value on a global scale.
Perovskite nanocrystals (PNCs) are emerging luminescent materials for a wide range of technological applications. Inspired by the mechanism of natural protection of leaves, this paper proposes natural carnauba wax (CW) as an encapsulation material for PNCs. The synthesis of PNCs is performed in the presence of CW, which is derived from the leaves of Copernicia prunifera palm. CW acts as a solvent and replaces the commonly used octadecene in the preparation of PNCs. The facile synthesis in CW results in PNCs with greatly improved thermal, water, and air stability. Furthermore, the thermal and mechanical properties make PNC-Wax a highly suitable solid ink for versatile processing of these materials into 2D and 3D architectures. PNC-Wax can be printed via a pen-on-paper approach by heating at modest temperatures.
