Lead sulfide quantum 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. Current review delves into the diverse fac
