In the present paper, we have reported room temperature synthesis of CTAB capped CdTe quantum
dots in an aqueous medium for free radical scavenging assay choosing BHA as the reference free radical.
The formation of CdTe QDs required relatively shorter reaction time with quantum yield up to 40 %. Their
optical properties, surface morphology and structural characterizations were employed through UV-Visible
absorption spectroscopy, Photoluminescence, FE-SEM, Powder-XRD, Raman spectroscopy and DSC-TGA
techniques. These QDs showed maximum absorption at 551 nm and their shape was spherical with average
particle size of about 3-4 nm as noted by surface morphology. The results showed that the synthesized
CdTe QDs have an excellent antioxidant activity. This type of semiconductor quantum dot is a promising
material for the upcoming generation in high speed optics and biomedical fields.
