Abstract
Seed-mediated growth, a straightforward technique with a low reaction temperature and low cost, was used to create multi-functional core/shell nanoparticles (CdTe@FeOOH). X-Ray Diffraction (XRD), High-resolution transmission electron microscopy (HTEM), Energy-dispersive x-ray (EDX), Fourier-transform infrared techniques (FT-IR), and Differential Thermal Analysis (DTA) were utilized to study the structure and composition of the as-prepared CdTe@FeOOH quantum dots (QDs). Photoluminescence (PL) properties of CdTe@FeOOH (Core/Shell) in an aqueous solution were studied by steady-state and time-resolved PL spectroscopy. The PL lifetime of CdTe@FeOOH QDs was reduced as a consequence of PL quenching. This results in the electron transfer mechanism being efficient, which reduces electron–hole recombination in the core–shell composite. The utilization of core–shell nanospheres of this nature presents numerous potentialities for applications in the field of photocatalysis.
