| Research Abstract |
This project was aimed at producing 1nm size of atomically perfectly mono-sized nanoparticles such as (CdSe)_<13>, (CdSe)_<33>, (CdSe)_<34> of II-VI semiconducting CdSe having excellent optical properties. These extremely small samples are analyzed to find conditions to achieve maximum efficiency of photo luminescence realized by loss less excitation relaxation process in precise and uniquely defined atomic arrangements.
