Lead sulfide nanoparticle dots (QDs) represent a fascinating class of materials with exceptional optoelectronic properties due to their unique size-dependent band gap. These QDs exhibit tunable absorption and emission spectra in the visible region, making them highly desirable for a wide range of applications. This review delves into the diverse f

Chemical formulas serve the elements of matter. Grasping these formulas is a fundamental understanding for exploring the complex world of chemistry. They encode information about the kinds of atoms existing in a substance, as well as their relative quantities. A chemical formula can quickly depict the combination of atoms within a molecule, provid
