Abstract:
Semiconductor nanocrystal quantum dots (QDs) are light emitting materials that
have been used in various applications such as bioimaging, biolabeling, sensors, lightemitting
diode (LED), and drug delivery. Due to the widely used QDs, such as CdSe, CdS,
and CdTe QDs, contain the heavy metal that might lead to much concern about their toxicity
and environmental impacts, alternative QDs with different compositions are of our interests.
In this study, zinc selenide/zinc sulfide (ZnSe/ZnS) coreshell QDs were synthesized by hotinjection
method. The ZnSe/ZnS QDs were characterized using UV-VIS, fluorescence
spectroscopy and TEM. The photoluminescence of ZnSe/ZnS QDs was blue with the
emission wavelength of about 400-450 nm and FWHM of about 20-30 nm. TEM images
showed size and structure of ZnSe/ZnS QD nanoparticles. The average diameter of particles
was 3.7±0.4 nm. From our study, ZnSe/ZnS QDs were coated with thiol-modified
polyamidoamine (PAMAM) polymer in order to improve dispersibility in aqueous phase.
Low cytotoxicity and potential for biological applications of the new water-dispersible
ZnSe/ZnS QDs were studied in comparison with the conventional CdSe/ZnS core-shell QDs.
