Nanostructures and Nanophosphors

Today Nanoscience and Nanotechnology are not only highly developed arenas of human endeavours but also some of the fastest growing branches of science and technology with ramifications into multitude of areas such as Nano-medicine, Quantum Well lasers, Solar Energy, Nano-electronics and Devices and Quantum Computations etc. Bio-conjugated ZnO quantum dots were prepared using wet chemical method and these quantum dots find applications in cancer therapy, imaging and phosphor applications. Highly luminescent, transparent, bio-compactable (non toxic) ZnO quantum dots were prepared using physical methods. ZnMgO/ZnO quantum wells were grown by PLD at low temperatures and strong room temperature UV photoluminescence was observed. Room temperature UV photoluminescence from ZnMgO/ZnO quantum wells TEM image of ZnO nanocrystals.

Luminescent semiconductor nanocrystal, termed as nanophosphors have been extensively studied during the last decade due to their unique optical properties which makes them ideal for a wide spectrum of applications ranging from flexible displays, lasers to biological imaging and therapeutic agents.ZnO is a highly multifunctional material with highly promising application potential for UV light emitting diodes, diode lasers, sensors, etc. ZnO nanocrystals and nanorods doped with transition metal impurities have also attracted great interest, recently, for their spin-electronic applications.
