The colour of the fluorescence of colloidal solutions of CdS nanoparticles depends on their size, changing from blue for small particles (1.7 nm), through green and yellow to orange red for 6 nm particles. This means that the energy of the emitted light decreases with increasing particle size. Explain this effect.
