Název v původním jazyce

Synthesis of quantum dots by microwave irradiation

Popis výsledku v původním jazyce

A microwave irradiation reduction way in an aqueous solution has been used for the synthesis of CdTe quantum dots using Na2TeO3 as the Te source and sodium borohydride as reduction agent. Quantum dots have been stabilized by mercaptosuccinic acid (MSA),where different amounts of added stabilizer have been studied. The synthesis parameters as power, reaction time, temperature and pH of the reaction solution have been optimized. According to reaction conditions size of prepared quantum dots can be tuned.Very short reaction time (10 - 15 min) and temperature from 50 to 130 degrees C suffice to prepare highly luminescence dots. Absorption spectra and photoluminescence spectra were measured to characterize prepared dots in water solution. The peak positions in the absorption spectra ranged from 470 nm to 652 nm and the photoluminescence emission peaks ranged from 500 nm to near infrared region (NIR) 720 nm.
