Abstract
Carbon is one of the unique elements in the world. Although several materials have only carbon atoms, different crystal structure and carbon atomic bonding generates different material properties. When size and shape of carbon configuration down to nanometer scale, new and interesting material properties (optical, mechanical,
electrical properties) emerge. Several carbon based nanoparticles are carbon nanotubes, graphene, graphene dots, fullerene, polymer dots, carbon dots, etc.
In this seminar, I will present carbon dots nanoparticles, which has unique fluorescence properties. Synthesis, optical properties, and applications of carbon dots will be briefly described based on experimental results in Research Center for Physics, LIPI, South Tangerang. Synthesis of carbon dots is very simple by utilizing
natural resources and waste that can be found in our daily life. Carbon dots have interesting fluorescence properties, so that a series of experimental measurement have been done to reveal the origin of the fluorescence. Furthermore, carbon dots are potential for many advanced applications, such as photo-catalyst, heavy metal
sensor, solar cells, LEDs, bio-tagging, etc. Several experimental results leading to application of carbon dots will be presented.
In addition, I will describe several research policies in Kedeputian Ilmu Pengetahuan Teknik (IPT) LIPI that will encourage collaboration research between universities and LIPI.
