Silver bromide is a chemical compound made up of silver and bromine, with the formula AgBr. It is a pale yellow solid that is primarily used in photography, particularly in traditional film and photographic paper. When exposed to light, silver bromide undergoes a chemical change, forming metallic silver, which creates an image. In addition to photography, silver bromide has applications in medical imaging and photovoltaic cells. It is also used in some types of antimicrobial coatings due to its ability to inhibit the growth of bacteria. However, it must be handled carefully, as it can be sensitive to light and moisture.
