Surface functionalization of core-shell QDs for solar photovoltaic and anti-cancer applications

Abstract

We undertook this present study; a simple and straight forward approach is developed to achieve CdSe/ZnS core-shell quantum dots by hydrothermal method and change the different hydrazine hydrate concentrations. As prepared QDs were characterized by high-throughput techniques and are tested for cytotoxicity activity against breast cancer cell line (MDA-MB-231) and testing in to sensitized solar cells (QDSSC) respectively. Further, the results study also revealed that, CdSe/ZnS QDs display unique tunable size, which is evidenced by transmission electron microscopic studies and optical properties (UV-Visible) studies. Moreover, FT-IR spectral investigations provide information about the interaction of trisodium citrate and hydrazine hydrate role in the surface functionalization and found plausible reason. The hydrazine hydrate modified CdSe/ZnS QDs (CZT-10) show an impressive anticancer activity in breast cancer cells and photovoltaic efficiency. This study open new avenues to find vital play on development of nanomaterial in the field of energy and environment application.
