| Abstract: | This paper describes the aging phenomena of colloidal CdS, using fluorescence emission results. It is known that particles of different sizes have not only different absorption spectra but also different fluorescence spectra. This effect is not surprising, because excitation at different wavelengths leads to the excitation of different size particles that do not have the same fluorescence intensity at the wavelength where the fluorescence is recorded. |
