October 11, 2023 – Faculty of Sciences, Khon Kaen University, organized a special forum on “Quantum Dot: An Amazing Discovery and Research on Chemical Sensor” at Wittayawipas Room 1, Wittayawipas Building, Faculty of Sciences. The event also featured a special talk by Prof. Wittaya Ngoenthae, Ph.D., a lecturer of the Department of Chemistry and the forum led by Assoc. Prof. Teerapong Puangmali, Ph.D., a lecturer from the Material Science and Nanotechnology Program, Department of Physics. Around 170 people, including lecturers, students and interested public attended at the Faculty and 140 others attended via Zoom Meeting.
The special forum was on “Quantum Dot”, which is an infinitesimal nanomaterial with outstanding properties. Nobel Prizes in the field of Chemistry of 2023 were presented to 3 scientists who discovered and synthesized Quantum Dot, namely, Moungi G. Bawendi, from Massachusetts Institute of Technology (MIT), USA; Louis E. Brus, from Columbia University, USA; and Alexei I. Ekimov, from Nanocrystals Technology Inc., USA.
Attendants were introduced to Quantum Dot, a material of the size of nanometer. The material has the property in absorbing, and its fluorescent property differs when the size changes. These outstanding properties result in its variety of use such as in Quantum Dot Light Emitting Diode (QLED) television, chemical sensor for sensing very small materials, high-efficiency quantum dot solar cell, and medical application of quantum dot for biological imaging.
From these outstanding properties and a lot of technological applications, “Quantum Dot” is comparable to a seed of nanotechnology. In order to honor the 3 scientists who discovered and synthesized this material, the award presentation ceremony, of the Nobel Prize in Chemistry of 2023, was also held on this occasion. The forum was of interest among the attendants, and acknowledged them on the properties and applications of Quantum Dot in various technologies.
