Abstract

A convenient and efficient one-pot synthesis method was employed to produce Thioglycolic Acid (TGA) capped Zinc Sulfide (ZnS) Quantum Dots (QDs). Compared to other QDs like CdSe, CdS, CdTe, and ZnSe, confining ZnS QDs was observed to be remarkably sensitive and challenging. Transmission electron microscopy characterization reveals a uniform dispersion of ZnS Quantum Dots (QDs) with an average diameter of 1.2 nm. Complementary calculations using the Bruce equation also estimate a size of 1.5 nm, affirming the consistent size of the QDs. The optical properties analysis indicates an initial optical band gap of 4.01 eV at room temperature. Notably, an intriguing observation is the reduction in band gap as temperature rises. Moreover, the size of the QDs was observed to increase with temperature, while the Urbach energy, revealing of localized states in the bandgap, also exhibited an increase with rising temperature. These temperature-dependent optical properties highlight the tunability of ZnS QDs, which could be advantageous for various applications. The Photo Luminescence (PL) response of the ZnS QDs exhibited a broad blue Photoluminescence band when subjected to a temperature of 90°C. This blue emission is a favourable characteristic for blue light emitters, making ZnS QDs potential candidates for applications in optoelectronic devices and displays. The Fourier-transform Infrared Spectroscopy (FTIR) spectra provided evidence for the successful encapsulation of ZnS QDs with TGA as the capping agent, further supporting the stability and passivation of the QDs’ surfaces.
