About Program







This is part of its efforts to popularize science to the general public and students who are pursuing science as their career. TNSF attempt to focus on students on higher science as everyone knows that learning of science at college within the curriculum is not enough to acquire holistic knowledge of science at the appropriate time. Hence, to fill the gap between what students are acquiring through the curriculum and what it is required, TNSF is planning its activities on higher science to students who are pursuing higher education.



About the Lecture
The 2023 Nobel Prize in chemistry was awarded to Moungi G. Bawendi, Louis E. Brus and Alexei I. Ekimov on 4th Oct 2023 for the discovery and synthesis of quantum dots. These nanoparticles have wide-ranging applications across fields like electronics, advanced surgery, and quantum computing.

What are quantum dots?
Quantum dots are particles that are a few nanometres wide. They exhibit unique optical properties due to their small physical size. Their structure and atomic composition are the same as bulk materials, but the properties of the latter don’t depend on their size.
In fact ,the properties of quantum dots can be changed by changing their size.

ஒரு நானோ படிக குறைகடத்தி குவாண்டம் புள்ளி (Quantum dot, சுருக்கமாக QD ) என அழைக்கப்படுகிறது. இது ஒளியை உமிழும் பண்புகளை பெற்ற நானோ துகள் ஆகும். இந்த துகள்களின் எக்சைடான்கள் (excitons) மூன்று அச்சுகளிலும் குவாண்டம் எல்லையால் கட்டுப்படுத்தப்படுகிறது. எனவே இது ஒரு பூஜிய பரிமாண துகள் ஆகும்.
