Development of phosphor materials and its applications

We introduce the facile synthesis route of luminescence materials without using non rare-earth materials. The luminescence materials consist of Graphene quantum dots and BCNO prepared by hydrothermal synthesis method and thermal decomposition method. In this research, we also study the mechanism of fluorescence of PL materials and also develop a thermoluminescence for dosimetry materials.

Research on reduced-Graphene Oxide

In this research, we purpose the facile and safe route synthesis method of reduced-Graphene oxide through the wet chemical processing. Particularly, we use ethylene glycol-microwave assisted method as the modification of Hummer’s and Marcano’s method. rGO is then used as the transparent conductive film, carbon electrode, photocatalyst and others.

Research on Hybrid Perovskite Materials

The hybrid perovskite materials, CH₃NH₃PbX (X=I, Cl,….), are synthesized by using abundant materials of lead source in Indonesia which is extracted from solder wire. The photovoltaic properties of hybrid perovskite are able to be used as solar energy harvesting. We also develop the single crystal of hybrid perovskite.
