Laser Annealing of Trap States in ZnSe Quantum Dots

Abstract

Our study of ZnSe quantum dots is motivated by the inherent interest in quantum confined systems and by the potential for shorter wavelength laser operation enabled by blue-shifted quantum confined energy levels. The optical and electronic properties of these nanocrystals as a function of the fabrication process were investigated with various optical techniques including photoluminescence (PL) lifetimes, and absorption, PL , and excitation spectroscopy.
