👉 Photofission refers to a process in which light or other electromagnetic radiation is absorbed, transformed into heat energy, and then released as a photon. This emission can be seen as a form of spontaneous emission, where a photon spontaneously creates a new state of matter or energy without any energy loss or conversion. Photofission has been observed in various materials, including glass, ceramics, and some metals, where photons are emitted during the process of crystal growth or chemical reaction.
