silver bromide
Noun: A light-sensitive chemical compound consisting of silver and bromine, used primarily in the photographic process. It is a pale yellow, water-insoluble salt that darkens upon exposure to light, forming the basis of traditional photographic film and paper emulsions.
This term is used in technical and scientific contexts, particularly in chemistry and photography. - It functions as a mass noun, typically used without a plural form when referring to the substance. - It is often found in phrases describing its application, such as "emulsion containing silver bromide" or "crystals of silver bromide."
- In a sentence:
- Traditional photographic film is coated with an emulsion of silver bromide in gelatin.
- The development process converts the exposed silver bromide into metallic silver, creating the image.
- In technical writing:
- The sensitivity of the emulsion depends on the size and distribution of the silver bromide crystals.
- In historical context: The dominance of silver bromide in photography throughout the 20th century is often discussed in histories of technology.
- The invention of gelatin silver bromide emulsions revolutionized photography in the 1870s.
- In scientific research: Refers to its properties in photochemistry and materials science.
- The study examined the latent image formation in silver bromide microcrystals.
- Silver halide: A broader class of light-sensitive compounds including silver bromide, silver chloride, and silver iodide.
- Photographic emulsion: The light-sensitive coating containing silver halide crystals, such as silver bromide, suspended in gelatin.
- Bromide: A compound of bromine with another element or group. Silver bromide is a specific type of bromide salt.
- AgBr (Chemical formula)
- Photographic silver halide (in a general photographic context)
