Photophysics is the study of the interaction between light and matter, focusing on how light is absorbed, emitted, and transformed into other forms of energy in various materials. This field of research involves the investigation of the fundamental processes that occur in molecules and materials when they are exposed to light, such as excitation, relaxation, and emission of photons. Photophysics research plays a crucial role in a variety of applications, including solar energy conversion, organic light-emitting diodes, and fluorescence imaging techniques. By studying the photophysical properties of materials, scientists can gain a deeper understanding of their behavior and develop new technologies and devices for a wide range of applications.
