Abstract In this paper, we report silk fibroin (SF) and carbon quantum dots (CQDs) nanocomposites obtained through a facile solution casting approach. The optical properties of the have been characterised by UV–vis absorption photoluminescence spectroscopy. Crosslinking SF chemical interactions with CQDs investigated FTIR addition, water stability degradability prepared composites in terms mass...

We investigate exciton states theoretically in strained GaN/AlN quantum dots with wurtzite ~WZ! and zinc-blende ~ZB! crystal structures, as well as strained WZ GaN/AlGaN quantum dots. We show that the strain field significantly modifies the conductionand valence-band edges of GaN quantum dots. The piezoelectric field is found to govern excitonic properties of WZ GaN/AlN quantum dots, while it h...

objective(s): a large ratio of surface to volume of nanoparticles in comparison with bulk ones, will increase the cell penetration and therefore their toxicity. materials and methods: chemical precipitation method was used in order to synthesis of zns:ag quantum dots. their physical properties and characteristics were assessed by x-ray diffraction, ultra violet-visible spectrophotometer, transm...

Carbon quantum dots (CQDs) have been emerged as a potent competent to classical metal-based semiconductor owing their fascinating characteristics such high biocompatible nature, solubility in water,...
