엽록소 형광
Chlorophyll + hν (blue/red) → Chlorophyll* → Chlorophyll + hν (red)
개요
Chlorophyll absorbs blue (430 nm) and red (660 nm) light, reaching an excited singlet state. Most energy is transferred to the photosynthetic reaction center, but a small fraction (1–2%) is re-emitted as red fluorescence (680–740 nm). This fluorescence is a direct indicator of photosynthetic efficiency.
일상 속 예시
If you shine a UV light on a spinach extract, it glows red due to chlorophyll fluorescence — a common chemistry demonstration.
