Abstract
A simple one dimensional potential well model has been employed to understand the photoluminescence from ZnO QDs The radius of the QDs being much larger than the Bohr radius weak confinement effect was observed UVvisible spectrum was used to calculate the band gap of the QDs The value of the band gap also suggests that the confinement effect is very weak We designated various energy levels corresponding to different emission peaks with different quantum numbers n This study will help in understanding the photoluminescence from ZnO nanostructures in a different way
