The nature and the performance of molecules and energy at that level are referred to as quantum physics. Quantum physics is the science in which the quantum reality has an effect. Quantum dots are semiconducting Nano crystals with diameters in the range of 2-10 nanometres. It concerned with the recent development of carbon quantum dots regarding their optical and photo luminescence mechanism, core structure. It brings about the most recent technological advancements in biological fields such as bio imaging and bio-assays which will be explained by eminent researches in the field of nanophysics. In Applied physics Conference, this session introduces the new sub-tracks for both physics and nanotechnology in the sectors.
