5,10,15,20-tetraphenylporphyrin photoluminescence on nanoporous silicon substrates

Photoluminescence of 5,10,15,20-tetraphenylporphyrin (H2TPP) on nanoporous silicon substrates has been studied. Used nanoporous silicon has a visible PL in the region of H2TPP absorption. Reradiation of porous silicon photoluminescence to the tetraphenylporphyrin long-wavelength peak of the photoluminescence spectrum is observed. The substrate microrelief plays a major role in the formation of tetraphenylporphyrin crystalline structures. The microrelief size of porous silicon was controlled by changing the technological parameters of electrochemical etching.
