Synthesis and Characterization of Wavelength-Tunable, Water-Soluble, and Near-Infrared-Emitting CdHgTe Nanorods

Abstract

Water-soluble alloyed CdHgTe nanorods were synthesized in aqueous media using CdTe nanorods as a template. Their emission spectra were in the near-infrared and tunable according to material compositions (red-shifted with increased Hg content).

Near-Infrared Fluorescent Materials for Sensing of Biological Targets

“…A number of core-shell NIRF QDs has been reported, such as CdHgTe/ZnS nanocrystals [34,40-42], CdHgTe nanorods [43], CdZnTe [44], InAs/CdSe/ZnSe core/shell1/shell2 (CSS) structure [45], silicon QDs [46-48], etc. The core-shell structure of QDs is popular because it provides a higher fluorescence quantum yield.…”

Solvothermal synthesis of Hg1−xCdxTe nanostructures—Their structural and optical properties

“…However, these techniques are ordinarily costly and complex in fabricating materials [2]. Recently there are few reports on the growth of MCT by colloidal synthesis [3,4]. Its optical properties are widely used for the fabrication of high performance photoconductive and photovoltaic detectors.…”

Defect related luminescence in Hg0.2Cd0.8Te nano- and micro-crystals grown by the solvothermal method

“…However, these techniques are costly and complex in the process of fabricating the materials [2]. Most recently, people have attempted the growth of MCT by colloidal synthesis, which shows blue shift in the bandgap, i.e., towards NIR-visible region, thus quite useful in biological applications [3,4]. Its optical properties are widely used towards fabrication of high performance photoconductive and photovoltaic detectors.…”
