Principle

Fluorescence Spectrophotometer : Hitachi F-4000

Fluorescence Spectrophotometer : Hitachi F-4000

Principle

Fluorescence is a type of photoluminescence in which a molecule is promoted to an electronically excited state by absorption of UV/Visible / near IR radiation. The excited molecule then decays back to the ground state or lower-lying excited electronic states by emission of light. The emitted light is detected as an Fluorescence.
