| Abstract: | The luminescence and excitation spectra and kinetic characteristics of the luminescence of the adsorbates of magnesium phthalocyanine
(MgPhc) on SiO2 and the effect on them of surface hydration and finely dispersed platinum are studied. It is found that a structure that
improves hydration of the adsorbent surface appears on the platinized surface in the luminescence and excitation spectra.
It is assumed that the spectral structure is due to the complexes of MgPhc formed with water molecules, the hydroxyl cover
of the surface, and the surface centers of SiO2 modified by a Pt-catalyst.
