Fluorescentie & Fosforescentie<br />

• absorptie van fotonen<br />

– emissie straling: λ emissie > λ excitatie<br />

• fluorescentie<br />

– electronische transitie, ∆S = 0<br />

– snelle relaxatie (< 10-5 s)<br />

•fosforescentie<br />

– relaxatie gaat gepaard met ∆S<br />

– emissie van straling lange tijd ná bestraling
