Abstract
A simple wet chemical protocol has been developed to synthesize ultrafine CdS quantum dots (QDs) without using any reducing and capping agent resulting in the formation of QDs of size ~ 5 nm. High resolution transmission electron microscope (HRTEM) images revealed the size uniformity with the appearance of defect free lattice fringes. X-ray diffraction study confirms the crystallinity and purity of the material. The CdS QDs show very low absorbance in the visible region of wavelength. The band gap calculated from the absorption data was found to be 2.15 eV. The CdS QDs exhibit strong green photoluminescence due to direct band edge transition. The synthesized CdS QDs exhibit strong antifungal against A. niger. This study will help in quantifying the dose of CdS nanoparticles to achieve antifungal activity against A. niger.
