| description | 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. |
