Zinc selenide optical fibers.
200 μm MRSEC researchers have fabricated the first optical Fibers made from zinc selenide, using a high-pressure Chemical deposition technique invented in the MRSEC. Optical fibers are a cornerstone of modern science and technology, yet remain fundamentally limited by the types of materials from which they can be made. With these new ZnSe fibers, it is now possible to exploit the materials prop...
متن کاملSynthesis and characterization of luminescent cadmium selenide/zinc selenide/zinc sulfide cholinomimetic quantum dots.
Luminescent quantum dots conjugated with highly selective molecular recognition ligands are widely used for targeting and imaging biological structures. In this paper, water soluble cholinomimetic cadmium selenide (core), zinc selenide/zinc sulfide (shell) quantum dots were synthesized for targeting cholinergic sites. Cholinomimetic specificity was incorporated by conjugation of the quantum dot...
متن کاملGreen synthesis and antibacterial activity of zinc selenide (ZnSe) nanoparticles
Objective(s): Drug delivery is an engineering technology to control the release and delivery of therapeutic agents to target organs, tissues, and cells. Metallic nanoparticles, such as gold nanoparticles (AuNPs) have exceptional properties which enable efficient drug transport into different cell types with reduced side effects and cytotoxicity to other tissues.Materials and Methods: AuNP...
متن کاملCo-solvent enhanced zinc oxysulfide buffer layers in Kesterite copper zinc tin selenide solar cells.
A co-solvent, dimethylsulfoxide (DMSO), is added to the aqueous chemical "bath" deposition (CBD) process used to grow ZnOS buffer layers for thin film Cu2ZnSnSe4 (CZTSe) solar cells. Device performance improves markedly as fill factors increase from 0.17 to 0.51 upon the co-solvent addition. X-ray photoelectron spectroscopy (XPS) analyses are presented for quasi-in situ CZTSe/CBD-ZnOS interface...
متن کاملDEFECT CHARACTERIZATION AND PHASE ANALYSES OF COPPER ZINC TIN SULFIDE/SELENIDE by
This work characterizes defects and phases within Cu2ZnSn(S,Se)4 (CZTS(Se)), an earth-abundant material used to make thin film photovoltaic solar cells. Overall research efforts focus on improving the solar cell device efficiency with the hope that it can be produced at the terawatt energy scale and circumvent material supply bottlenecks of current thin film photovoltaic technology. In this wor...
