Study of Mn d-d emission mechanisms in II-VI semiconductor nano crystals

Abstract

With the advent of nanotechnology, many important fields have come up with the diverse applications in various interdisciplinary areas and indeed it has been observed that ‘there’s plenty of room at the bottom’ that was first quoted by the physicist Richard P. Feynmann. One of the most important scientific areas that have developed recently is Nanomaterials which ultimately lead to the emergence of nanotechnology. Nanomaterials show unique properties arising from their nanoscale dimensions. These special properties of the nanomaterials can be exploited to attain several useful applications. One such nanomaterial with huge potential are the Quantum Dots. These are tiny particles of the semiconducting material which confines the motion of conduction band electrons, valence band holes or excitons (bound pairs of conduction band electrons and valence band holes) in all three spatial directions.
