Phophorescence
WebMay 14, 2024 · Phosphorescence occurs when an intersystem crossing occurs, and electrons cannot return directly to the ground state, but instead make a transition to an intermediate state. They then relax slowly to the ground state, resulting in phosphorescence. Fluorescence occurs on a timescale of nanoseconds, whereas phosphorescence can … WebJun 2, 2024 · Fluorescence and phosphorescence are two mechanisms that emit light or examples of photoluminescence. However, the two terms don't mean the same thing and don't occur the same way. In both fluorescence …
