Non-linear emission spectra of quantum dots strongly coupled to photonic mode

open access: yes, 2010
A theory of optical emission of quantum dot arrays in quantum microcavities is developed. The regime of the strong coupling between the quantum dots and photonic mode of the cavity is considered. The quantum dots are modeled as two-level systems.

Brightly Luminescent and Color-Tunable Colloidal CH3NH3PbX3 (X = Br, I, Cl) Quantum Dots: Potential Alternatives for Display Technology.

open access: yesACS Nano, 2015
Organometal halide perovskites are inexpensive materials with desirable characteristics of color-tunable and narrow-band emissions for lighting and display technology, but they suffer from low photoluminescence quantum yields at low excitation fluencies.

Novel function of ribosomal protein RPL14B: regulation of CdSe quantum dots biosynthesis in living Saccharomyces cerevisiae cells

open access: yesMicrobial Cell Factories
Biosynthesis of CdSe quantum dots is the process of converting metal ions into semiconductor nanomaterials. Studies have shown that CdSe quantum dots synthesized by Saccharomyces cerevisiae are rich in ribosomal proteins, but the role of ribosomal ...

Structurally Colored Physically Unclonable Functions with Ultra‐Rich and Stable Encoding Capacity

open access: yesAdvanced Functional Materials, Volume 35, Issue 12, March 18, 2025.
This study reports a design strategy for generating bright‐field resolvable physically unclonable functions with extremely rich encoding capacity coupled with outstanding thermal and chemical stability. The optical response emerges from thickness‐dependent structural color formation in ZnO features, which are fabricated by physical vapor deposition ...

Optically Generated 2-Dimensional Photonic Cluster State from Coupled Quantum Dots [PDF]

open access: yes, 2010
We propose a method to generate a two-dimensional cluster state of polarization encoded photonic qubits from two coupled quantum dot emitters. We combine the proposal for generating one-dimensional cluster state strings from a single dot, with a new ...
