Dye-Aggregation
The absorption of light results in dye molecules entering an electronically excited state, which can store energy only for a brief period and can be radiated again during fluorescence after the excited state's lifetime.

1,3-Thiazole building blocks in natural products and synthetic materials
Thiazole, also known as 1,3-thiazole, is a five-membered heterocyclic compound containing both sulfur and nitrogen. The term "thiazole" also refers to a large group of derivatives. Thiazole itself is a pale yellow liquid with a pyridine-like odor and the molecular formula C3H3NS.[1,2] The ...
Perovskite Quantum Dots (PQDs)
Perovskite generally refers to a kind of material with similar crystal structure to perovskite, which is composed of perovskite oxide (CaTiO3).
Fluorescence Quenching
The fluorescence of a compound can be quenched, meaning it is reduced or completely switched off by processes that do not destroy the fluorophore permanently. Fluorescence quenching reduces the intensity of fluorescence, but the original intensity reappears as soon as the quencher is removed or ...
Applications of Quantum Dot Technologies in Cancer Detection and Treatment
Early screening of cancer is desirable as most tumors are detectable only when they reach a certain size when they contain millions of cells that may already have metastasized.
Fluorescent Probes - Absorption and Fluorescence
Besides the optical phenomena of refraction, scattering, interference, and diffraction in partially or totally transparent objects, which can result in colour impressions such as rainbows, sky blue, sparkling soap bubbles, gorgeous peacock feathers, or thin oil films and layers, the colours of ...
Quantum Dots for Electronics and Energy Applications
Quantum dots (QDs) are semiconductor materials at the nanoscale (~2-10 nm). Due to their small size, quantum dots exhibit quantum confinement effects as well as size-dependent electrical and optical properties. Since the discovery of cadmium-based QDs in the 1980s, a variety of cadmium- and ...
Optimizing Quantum Dots to Maximize Solar Panel Efficiency
Researchers in Australia have developed an algorithm that accurately calculates the size and density of quantum dots needed to boost solar panels to maximum efficiency. Researchers at Monash University in Australia, which is a member of the Australian Research Council's ARC Centre of Excellence ...
A New Role for Angiotensin II in Aging
Control of fluid volume homeostasis is essential for life, and the complex systems dedicated to this task in humans are the result of evolutionary processes shaped by survival responses.
