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. Recent review delves into the diverse

Chemical formulas serve the building blocks of matter. Interpreting these formulas provides a fundamental understanding for exploring the vast world of chemistry. They reveal information about the species of atoms present in a compound, as well as their relative quantities. A chemical formula can simply illustrate the combination of atoms within a
