Porous superstructures are characterized by a large surface area and efficient molecular
transport. Although methods aimed at generating porous superstructures from nanocrystals …

Programmable organization of functional inorganic nanoparticles (NPs) into well-defined
hierarchical superstructures has raised considerable concern due to the enhanced …

Understanding the fundamental excited-state dynamics of quantum dot thin films is key to
rationally engineering high quality devices. However, studying the radiative and …

Lead-halide perovskite nanocrystals have recently emerged as desirable optical materials
for applications such as coherent quantum light emitters and solid-state laser cooling due to …

Correlated orientational disordered phase is a thermodynamic phase with the constituent
particles following some conserved laws or correlation despite the orientational disorder …

This dissertation is composed of 7 chapters discussing optical studies performed in thin film
samples. These studies are separated in two parts. Part I focuses on studies performed on …
