Abstract: Colloidal quantum dots (CQDs) are a novel class of materials which provide an avenue to explore the quantum confinement effects in semiconductors. Due to their high degree of size controlled spectral tunability, they are being widely pursued as the next generation materials for display and solid state lighting applications. Single material CQDs covering the full visible spectrum merely by size control offer a unique solution for the current laser technology. The most desired full color single material lasers would possibly be enabled by this novel material with the most cost effective approach. This MS thesis work aims to study the properties of CQDs along with their excitonic dynamics towards applications in lasers. Here the study of quantum confinement effects and the optical gain in CQDs is carried out. Also, a detailed simulation study of lifetime decay characteristics of excitonic states is performed. The results indicate that CQD lasers hold great promise for our future research work in versatile lasing platforms.
