Energy/Electron Transfer Switch for Controlling Optical Properties of Silicon Quantum Dots

development of different optical methods for determination of glucose using cadmium telluride quantum dots and silver nanoparticles

a simple, rapid and low-cost scanner spectroscopy method for the glucose determination by utilizing glucose oxidase and cdte/tga quantum dots as chromoionophore has been described. the detection was based on the combination of the glucose enzymatic reaction and the quenching effect of h2o2 on the cdte quantum dots (qds) photoluminescence.in this study glucose was determined by utilizing glucose...

Optical, Thermal and Structural Properties of CdS Quantum Dots Synthesized by A Simple Chemical Route

The present work deals with the synthesis and characterization of CdS nanoparticles with good thermal stability and optical properties by a novel and simple synthetic route. The nanoparticles were synthesized via chemical precipitation method in a single reaction vessel under ambient conditions. The prepared CdS nanoparticles were compared with the bulk CdS. The Optical properties were determin...

Synthesis and Optical Study of CdZnTe Quantum Dots

The comparison of growth processes and fluorescent properties of CdZnTe semiconductor quantum dots that are synthesized in different concentrations of Zn2+ in water are discussed in this paper. The samples are characterized through absorbtion (UV) and photoluminescence spectra (PL). The results show that when the reaction time is prolonged, the absorption peak and fluorescent emission peak pres...
