Effects of Zn (II) on the Optical Properties of CdTe Quantum Dots and Their Photoluminescence Response to Lead Ion
نویسندگان
چکیده
Water-soluble CdTe quantum dots (QDs) have been utilized as photoluminescence probes for the detection of metal ions such Pb2+, Hg2+, Cd2+, etc. We initially developed highly (PL) Zn-doped toxic detection. A study on changes optical properties and QDs when exposed to Pb2+ suggested that could act a surface passivating agent reduce Te2- dangling bonds while Zn2+ dopant stabilizes against ambient oxidation. The results demonstrated herein provide useful understandings interactions between water-soluble ions. These suggest further applications in sensing

Fingerprint identification or dactyloscopy is a method for human identification. The impressions left by a human finger on surfaces are not visible to naked eyes (latent fingerprint); therefore, they require revelation to become visible and identified. Within the last century, several fingerprint revelation techniques such as optical, physical, and chemical were studied. These traditional metho...
متن کاملdevelopment 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...
