By using the concepts of Thermal radiation ,we come to know that a particular sensitizer can absorb photons of one wavelength and release photons of a longer wavelength is because the longer wavelength has less energy.

We know very well that every objects in this universe wants to remain stable. For achieving stability either it requires some energy or it need to release extra energy.

We know that E=[tex]\frac{hc}{wavelength}[/tex]

So to achieve stability, sanitizer have to release some extra energy, we can see that energy is inversely proportional to wavelength, means when amount of energy is less it means wavelength will be longer,

Hence, a sensitizer releases longer wavelength as longer length have lesser energy.
