Fluorescence: bright light in the world of chemistry
Fluorescence is a phenomenon that occurs when a substance emits light after it absorbs radiation of a different wavelength. This phenomenon is caused by the transition of molecules from an excited singlet state to the ground state. Fluorescence has been known for more than a hundred years and has found wide application in science, industry and medicine.
The history of the discovery of fluorescence began in 1852, when it was first observed that ultraviolet light caused a bright shine in a solution of quinine. This phenomenon was subsequently found to be due to fluorescence, which occurs when quinine molecules absorb ultraviolet light.
Today, fluorescence has found wide application in various fields of science. It is used to study the structure and properties of molecules, as well as to analyze biological objects. For example, in medicine, fluorescence is used to diagnose cancer and other diseases.
Fluorescence has also found application in industry. It is used to create bright dyes, light filters and light-insulating materials. In addition, fluorescence is used as a marker in various processes, for example to track the movement of liquids in pipes or to monitor product quality.
One example of the application of fluorescence is fluorescence microscopy, which allows the visualization of structures and processes inside living cells. This allows researchers to obtain more precise information about the functioning of cells and their interaction with the environment.
In conclusion, fluorescence is an amazing phenomenon that has wide applications in science, industry and medicine. This phenomenon allows researchers to obtain more accurate information about the molecular structure and properties of substances, as well as about the processes occurring inside living organisms. Of course, fluorescence will continue to be one of the most amazing and useful phenomena in the world of chemistry and science in general.
