The huge diversity of hierarchical micro-/nano-rigid structures existing in biological systems
is increasingly becoming a source of inspiration of materials scientists and engineers to …

Quantum dots (QDs) are nanocrystals made of semiconductors, which exhibit intriguing
electronic transitions that resemble single atom behavior. Due to their unique, size-tunable …

We have developed a simple approach for the preparation of carbon nanodots (C-dots) from
coffee grounds. As-prepared C-dots have an average diameter of 5±2 nm, of which quantum …

Although various colloidal quantum dot (QD) coating and patterning techniques have been
developed to meet the demands in optoelectronic applications over the past years, each of …

Analyzing food composition and detecting contaminants is important for monitoring food
quality and assessing public health risks. Traditional food analysis methods can meet …

Gold nanoclusters (Au NCs) stand for a new type of fluorescent nanomaterials with
outstanding optical properties due to their discrete electronic energy and direct electron …

A coupled semiconductor material is prepared by filling one-dimensional (1D) titania (TiO2)
nanotubes (NTs) with cadmium sulfide (CdS) nanoparticles (NPs). Self-assembled TiO2 NTs …

For the first time, we report a simple method to fabricate a quantum dot (QD)− polymer
composite completely via aqueous media from synthesis of QDs to formation of composite. A …

Colloidal semiconductor nanoplatelets (NPLs) are highly promising luminescent materials
owing to their exceptionally narrow emission spectra. While high-efficiency NPLs in non …

N-doped carbon dots were successfully synthesized via a one-step hydrothermal method by
using edible winter melon as the source material. Mono-dispersed CDs 4.5–5.2 nm in …
