Phosphorescence definition for kids
WebThe radiative decay from an excited triplet state back to a singlet state is known as phosphorescence. Since a transition in spin multiplicity occurs, phosphorescence is a manifestation of intersystem crossing. The time scale of intersystem crossing is on the order of 10 −8 to 10 −3 s, one of the slowest forms of relaxation. Metal Complexes Webphosphorescence in American English (ˌfɑsfəˈrɛsəns ) noun 1. a. the condition or property of a substance of giving off a lingering emission of light after exposure to radiant energy, as light or X-rays b. the light thus given off 2. a continuing luminescence without noticeable heat, as from phosphorus when it is slowly oxidized
