Lead sulfide semiconductor 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

Chromium oxide is a metallic compound with a remarkable range of physical properties. It presents in check here various forms, including chromium(III) oxide (Cr?O?), also known as chromia, which exhibits excellent durability. This oxide demonstrates high melting resistances, making it suitable for high-temperature applications. Furthermore, chromi
